Job insecurity and its association with health among employees in the Taiwanese general population

Gender- and age-specific associations between psychosocial work conditions and perceived work sustainability in the general working population in Taiwan

OBJECTIVES

One aspect of work sustainability pertains to workers' intention to remain in their current job until reaching retirement age. Various adverse working conditions are expected to diminish work sustainability among different social groups. This study aims to examine these associations across gender and age groups.

METHODS

The study participants were 19,152 economically-active adults in a national survey conducted in Taiwan. Information concerning psychosocial working conditions were obtained through interviews, using the Job Content Questionnaire. Work sustainability was evaluated by one question that asked whether the participants felt they would be able to do their current job until the age of 60. The association between psychosocial work conditions and work sustainability was examined by logistic regression analysis. We further performed stratified analysis to explore age and gender-specific associations.

RESULTS

We observed that 14.2% and 17.1% of male and female workers reported low work sustainability. Workers in the electronics industries and female workers in the healthcare and education sectors reported low work sustainability. Gender-specific analyses showed that low job control among men and shift work among women were significantly associated with low work sustainability. Age-specific analyses indicated that having poor health, shift work, and long working hours in younger workers, and having low job control in older workers were associated with low work sustainability.

CONCLUSION

To retain older workers in the labor market, policies should aim at the improvement of psychosocial work conditions, and gender- and age-specific issues should be taken into consideration.

Cross-cultural adaptation of the Job Insecurity Scale (JIS) in Brazil and cross-national analysis of Job Insecurity effects in Brazil and Spain

BACKGROUND

Job flexibilisation has increased interest in job insecurity and its consequences. Job insecurity, understood as a fear of losing employment, is linked to a deterioration of mental health, social relations or job satisfaction. Its study has been developed primarily in Europe, in the absence of validated psychometric scales in the Latin American context. To bridge this knowledge gap, the aim of this study is to cross-culturally adapt the Job Insecurity Scale (JIS) in Brazil, and secondly, to establish a cross-national analysis between people employed in Brazil and Spain.

METHODS

As criteria for the sample, people with formally established employment in Brazil and Spain were selected. For the scale adaptation process, a sequence of EFA, CFA and validity tests are carried out, as well as a multigroup invariance according to the gender variable. The cross-national comparison compares the effect sizes of affective and cognitive job insecurity on the mental health variable measured with the GHQ-28 scale in both countries.

RESULTS

1165 employed people participate in the study, of whom 573 reside in Brazil and 592 in Spain. The results of the scale adaptation show that the JIS is suitable for use in the Brazilian employment context. The scale offers a factorialisation in two dimensions (affective and cognitive) (CFI = 0.993; TLI = 0.987; RMSEA = 0.04; SRMR = 0.049; GFI = 0.999; NFI = 0.980) with good reliability (ω > 0.84). The cross-national comparison shows that job insecurity has a greater weight in explaining the mental health of the employed population in Brazil than in Spain, which is related to higher indicators of job insecurity in the Brazilian context.

CONCLUSIONS

With this validation we now have a validated scale of job insecurity validated for the Brazilian context. The comparison between countries shows the need to establish these analyses, since the behaviour of the phenomenon is different in the contexts studied.

Psychosocial risk factors for low back pain in US workers: Data from the 2002-2018 quality of work life survey

BACKGROUND

Examining workplace psychosocial risk factors for back pain becomes increasingly important because of the changing nature of work and rising healthcare costs. Some psychosocial risk factors for back pain, such as work and family imbalance, exposure to a hostile work environment, and job insecurity, are understudied for the working population in the United States.

METHODS

Data used in this study came from the Quality of Work Life Survey (QWL), a supplementary module of the General Social Survey conducted in the United States. Data from the 2002, 2006, 2010, 2014, and 2018 QWL surveys were used in these analyses, giving a total sample size of 6661. Five domains of workplace psychosocial risk factors for back pain were examined, including job strain, low social support, work-family imbalance, exposure to a hostile work environment (harassment and discrimination), and job insecurity. The adjusted odds ratio (aOR) of each psychosocial risk factor for back pain with 95% confidence intervals (CI) was estimated using a multivariable logistic regression model after controlling for job physical factors, occupation, and demographic and socioeconomic characteristics.

RESULTS

Significant associations were found between back pain and several psychosocial factors including job strain (aOR 1.19; CI 1.00,1.41), work-family imbalance (aOR,1.42; CI 1.22,1.64), harassment (aOR 1.40; CI 1.15,1.71), and discrimination (aOR 1.20 CI 1.00,1.44).

CONCLUSION

This study contributes to the understanding of the relationship between a variety of workplace psychosocial factors and back pain. Our findings suggest directions in future longitudinal research to examine emerging workplace psychosocial factors for back pain.

The Double-Edged Sword of Safety Training for Safety Behavior: The Critical Role of Psychological Factors during COVID-19

Safety training (ST) is the primary means of avoiding unsafe behaviors, but it has not achieved the expected impact on improving workplace safety because of the high psychological stress it brings to workers. The coronavirus disease 2019 (COVID-19) further threatens workers' psychological conditions, thereby diminishing the effectiveness of ST. However, the existing literature has mainly laid emphasis on the bright side of ST and neglected examining its impact on safety behavior (SB) from detrimental psychological factors. Drawing from the conservation of resources theory, a novel two-staged model was established to understand how these psychological factors mediate and moderate the association between ST and SB. We incorporated resource consumption (e.g., role overload (RO) and COVID-19-related task setbacks) and resource generation (e.g., psychological resilience) into the model to consider both detrimental and protective psychological factors against ST. We then implemented a time-separated, three-wave data collection on a sample of frontline workers to validate this hypothetical model. Consistent with our hypothesis, RO played a significant mediating role between ST and SB, that is, ST leads to RO, and in turn, holds up SB. Surprisingly, contrary to our hypothesis, COVID-19-related task setbacks weakened the negative and indirect impact of ST on SB via RO. This is one of the first empirical studies to highlight how detrimental psychological factors caused by ST constrict or amplify SB. In practice, the efficacy of ST can be enhanced by cultivating psychological resilience and clarifying employees' job responsibilities to reduce the ambiguity of roles.

Negative Work Attitudes and Task Performance: Mediating Role of Knowledge Hiding and Moderating Role of Servant Leadership

The COVID-19 pandemic has caused a global crisis that particularly hit employment globally. Due to the economic crisis, many small businesses attempted to minimise their expenses by either closing or downsizing. During such organisational situations, the employees face negative workplace attitudes that lead to knowledge hiding and affect team performance. This study examines negative attitudes and their effect on team performance. Further, this study examines the mediating effect of knowledge hiding and moderating the role of servant leadership. Through a multi-time data collection approach, the authors obtained 363 responses from the education sector in China during the COVID-19 pandemic. PROCESS Hayes model 1 and 4 were used for mediation and moderation analysis. Results show that job insecurity, cynicism, and role stress are significant forces behind knowledge-hiding behaviour. Furthermore, the knowledge hiding behaviour adversely affects task performance. Servant leadership shows a buffering effect on knowledge hiding behaviour caused by negative workplace attitudes. This is one of the first studies in the South Asian environment to examine the association between employees’ negative attitudes and task performance using knowledge hiding as a mediator and servant leadership as a moderator in the COVID-19 scenario. Lastly, the paper concludes with a consideration of its theoretical, practical implication and future direction.

Taking stock and moving forward: A textual statistics approach to synthesizing four decades of job insecurity research

We collected the abstracts of manuscripts examining job insecurity published between 1984 and 2019 and carried out a textual analysis to investigate the defining clusters, their development over time, and whether there was evidence of siloed knowledge. Results suggested that job insecurity research seems to be fragmented into disciplinary foci (organizational psychology, public health, economics, and sociology). Further analyses on the organizational psychology corpus, revealed 25 topics with distinct temporal trajectories: some were increasing (analytical advances and differentiation between cognitive and affective job insecurity) while other were decreasing (scale development). The remaining abstracts revealed 15 topics with more stable trajectories. Based on these results, we identified five areas for future organizational research on job insecurity: the changing labor market, the need to better understand the experiences of marginalized workers and non-work outcomes of job insecurity, the added-value of qualitative research, and the need to critically evaluate our assumptions as researchers. Plain Language Summary Since the paper by Greenhalgh and Rosenblatt, research on job insecurity has burgeoned. Taking an interdisciplinary perspective, we collected the abstracts of all peer-reviewed manuscripts examining job insecurity published between 1984 and 2019 and carried out a textual analysis using the Latent Dirichlet Allocation and the Reinert method to investigate (a) the defining clusters of job insecurity research, (b) the development of such clusters over time, and (c) whether there was any evidence of siloed knowledge. Results suggested that indeed job insecurity research seems to be fragmented into four main disciplinary foci (organizational psychology, public health, economics, and sociology) with relatively little cross-fertilization. We conducted further analyses of the abstracts stemming from organizational research on job insecurity, revealing 25 topics with distinct temporal trajectories (e.g., “hot” topics including the increasing use of advanced analytic techniques and differentiation between cognitive and affective job insecurity) and “cold” topics including the development of job insecurity measures). The remaining abstracts revealed 15 topics with more stable research interests over time (e.g., a continued reliance on appraisal theories). Based on these results, we identified five areas for future organizational research on job insecurity based on: the changing labor market, the need to better understand the experiences of marginalized workers and non-work outcomes of job insecurity, the added-value of qualitative research, and finally the need to critically evaluate our assumptions as researchers.

Demographic Influences on Perceived Stressors of Construction Workers during the COVID-19 Pandemic

Construction work is one of the most stressful occupations in the world, and the COVID-19 pandemic has only exacerbated this reality. This research conducted a detailed investigation on the perceived stressors of different demographic groups among construction workers. Empirical data were collected using a structured questionnaire in the Chinese construction industry. The empirical data were processed using both an independent sample t-test and an Analysis of Variance (ANOVA). The findings indicated that male workers reported greater workloads than did females. Married workers experienced more pandemic fear and job insecurity, and they were more sensitive to the poor working environment. Highly-educated workers were inclined to be more satisfied with organizational pandemic responses, and had lower job insecurity and role ambiguity, but they experienced heavier workloads. In addition, the differences in work experience and age were statistically significant with regards to job insecurity. This research contributes to the body of knowledge by giving a comprehensive understanding of demographic influences on perceived stressors among construction workers. It also provides valuable insights to identify sensitive demographic groups and promote their health and wellbeing during and after the pandemic.

Job insecurity during the COVID-19 pandemic and counterproductive work behavior: The sequential mediation effects of job stress and organizational identification and the buffering role of corporate social responsibility

Swift social and economic environmental changes such as those associated with the COVID-19 pandemic have led to decreased job security. Although numerous previous studies have examined the influence of job insecurity on employee perceptions, attitudes, and behaviors, the link between job insecurity and negative behavior and its underlying or intermediating mechanisms remain underexplored. The significance of an organization's positive behaviors, which fall under the umbrella of corporate social responsibility (CSR), also deserves more attention. To address these gaps, we examined both the mediator and the moderator in the association between job insecurity and negative employee behavior by establishing a moderated sequential mediation model. We hypothesized that the levels of employee job stress and organizational identification sequentially mediate the relationship between job insecurity and counterproductive work behavior as a representative negative behavior. We also hypothesized that CSR activities play a buffering role that moderates the influence of job insecurity on job stress. We used three-wave time-lagged data collected from 348 employees in South Korean organizations to demonstrate that job stress and organizational identification sequentially mediate the relationship between job insecurity and counterproductive work behavior, and that CSR activities function as a buffering factor that decreases the influence of job insecurity on job stress. The results of this research suggest that the levels of job stress and organizational identification (as sequential mediators) as well as CSR activities (as a moderator) are underlying mechanisms in the link between job insecurity and counterproductive work behavior.

Theorizing to Improve Mental Health in Multicultural Construction Industries: An Intercultural Coping Model

Construction workers are exposed to a range of stressors that lead to mental ill-health. In a multicultural construction workplace, the interactions between workers with different cultural backgrounds may aggravate mental health issues. Existing studies on coping typically focus on a reactive approach to managing stressors in the absence of cultural-related factors. This approach is inadequate in addressing mental health issues in a culturally diverse construction workplace. This paper presents a critical review that synthesizes and analyses theories and models of stress and coping, proactive coping, occupational stress, acculturative stress, and intercultural competence to develop a conceptual model for managing mental health in a multicultural construction workforce. The proposed model relies upon a positive coping mechanism, i.e., intercultural coping, to manage stressful events during the entire coping process in a multicultural workplace, towards achieving sustained good mental health. The proposed conceptual model contributes to the development of coping theories and positive psychology approaches and provides effective coping strategies to enhance psychological well-being in a multicultural context.

Analysis of the 2012 Canadian Community Health Survey-Mental Health demonstrates employment insecurity to be associated with mental illness

A growing number of people depend on flexible employment, characterized by outsider employment and lower levels of job security. This study investigated whether there was a synergistic effect of employment status and job insecurity on mental disorders.This study used data from the 2012 Canadian Community Health Survey-Mental Health (CCHS) of 13,722 Canada's labor force population aged 20 to 70. Data were collected from January to December, 2012, using computer-assisted personal interviewing. As combining employment status with perceived job insecurity, we formed five job categories: secure full-time, full-time insecure, part-time secure, part-time insecure employment, and unemployment.Results showed that, regardless of employment status (full-time vs part-time), insecure employment was significantly associated with high risk of mental disorders. Furthermore, the odds ratios for insecure employment were similar to those for unemployment. Male workers who are full-time, but with insecure jobs, were more likely to experience mental disorders than female workers.This study's findings imply that while perceived job insecurity may be a critical factor for developing mental health problems among workers, providing effective health care services can mitigate an excessive health risk for the most vulnerable employment, especially for insecure part-time employment and unemployment.

Designing a Model via Grounded Theory to Reduce Agricultural Work Injury among Orchardists in Ilam Province

The present study aimed to design a model to reduce agricultural work injury among orchardists in Ilam Province, Iran. This was a qualitative research study that used grounded theory to analyze data. The study included 25 specialists, managers, and experts of horticulture in Ilam Province who were selected through purposive sampling. Field observations and interviews in the form of focus groups were used for collecting data. The results were extracted from the research data through the coding process (open, axial, and selective) in the form of concepts, subcategories, and categories using MAXqda12. The paradigm model included causal, contextual and intervening conditions, strategy, and consequences. The results indicated that several causal conditions can affect work injury in agriculture. These were identified as vulnerability level, personal characteristics of orchardists, subsistence level, general health, climatic conditions, and academic qualifications. Contextual conditions also included categories like trends, occupational safety and health principles, infrastructure, government support, and government incentives. Meanwhile, intervening conditions were identified as structural, educational-research factors, economic criteria, regulation and development of marketing horticultural and greenhouse products, type of exploitation system, and orchardists' motivation. Finally, reducing agricultural work injuries among orchardists involved the multi-faceted identification of various aspects of production and education, along with technical, operational, executive, and supervisory management strategies. Reducing the number of agricultural work injuries among orchardists would lead to regional, economic, individual, and social benefits. The results helped researchers to identify what areas to address and mitigate safety issues of horticultural activities in Ilam.

Clinician burnout during the COVID-19 pandemic before vaccine administration

Background

Coronavirus disease 2019 (COVID-19) has disrupted pharmacy practice. Little research has been done to assess how COVID-19 has affected pharmacists’ employment, workload, and feelings of burnout.

Objectives

The objectives of this study were to characterize the impact of COVID-19 on pharmacists’ employment status, workload, and feelings of burnout, as well as to examine emotional health concerns related to COVID-19.

Methods

Wisconsin pharmacists were surveyed using an online instrument between August 25, 2020, and September 22, 2020. The data analysis, performed in December 2020, examined employment status, 3 common burnout risk factors (workload, rewards, and social depersonalization), and emotional health concerns related to COVID-19.

Results

Of the 1300 pharmacists, 439 completed the survey (33.8%). The study analysis included pharmacists in community (n = 127) and hospital or health system (n = 107) settings. With regard to employment changes and workload, hospital pharmacists (36%) were more likely to have their hours reduced than community pharmacists (13%) (P < 0.01), and, conversely, community pharmacists (19%) were more likely to have their hours increased than hospital pharmacists (8%) (P = 0.01). For the burnout domain of workload, 45% of the pharmacists reported increased feelings of physical exhaustion at work, and 53% reported increased feelings of emotional exhaustion at work, with no difference between settings. Regarding the burnout domain of rewards, 6% of the hospital pharmacists and 1% of the community pharmacists experienced a reduction in hourly wages or salaries as a result of COVID-19. For the burnout domain of depersonalization, 25% of the pharmacists reported that their ability to connect with colleagues and patients decreased during the COVID-19 pandemic. Additional emotional health concerns reported by the pharmacists included 40% experiencing more anxiety and 25% experiencing more sadness or depression during the COVID-19 pandemic, with no difference between settings.

Conclusion

This study found that the burnout domains related to workload, rewards, and depersonalization were negatively affected by COVID-19. Pharmacy managers need to proactively combat burnout as well as be reactive when employees show signs of burnout to maintain their workforce and meet the COVID-19–associated challenges.

The Effect of Changes in Employment on Health of Work-Related Injured Workers: A Longitudinal Perspectives

This longitudinal study attempted to identify changes in employment status and overall health status. The participants were workers who had experienced work-related injuries in the past. In this study, we used the Panel Study of Workers’ Compensation Insurance from 2013 to 2017. This study utilized propensity score matching for a quasi-experimental design study of the first year to exclude the effects of the confounding variables and exclude the effect of employment status, which is the main independent variable. After applying propensity score matching the research subjects totaled 1070. Changes in employment status were found to have a negative effect on overall health status. This raises new implications for existing industrial accident-related support policies. Thus, it is considered that the scope should be expanded from policies related to re-employment of workers after an industrial accident to improving quality of life through maintaining employment from a long-term perspective. The notable point of this study was to apply the PSM methods. By applying PSM, we clearly identified the effect of changes in employment status on health status.

Is Job Insecurity Worse for Mental Health Than Having a Part-time Job in Canada?

OBJECTIVES

A growing number of people depend on flexible employment, characterized by outsider employment status and perceived job insecurity. This study investigated whether there was a synergistic effect of employment status (full-time vs. part-time) and perceived job insecurity on major depressive disorder.

METHODS

Data were derived from the 2012 Canadian Community Health Survey-Mental Health of 12 640 of Canada's labor force population, aged 20 to 74. By combining employment status with perceived job insecurity, we formed four employment categories: full-time secure, full-time insecure, part-time secure, and part-time insecure.

RESULTS

Results showed no synergistic health effect between employment status and perceived job insecurity. Regardless of employment status (full-time vs. part-time), insecure employment was significantly associated with a high risk of major depressive disorder. Analysis of the interaction between gender and four flexible employment status showed a gender-contingent effect on this link in only full-time insecure category. Men workers with full-time insecure jobs were more likely to experience major depressive disorders than their women counterparts.

CONCLUSIONS

This study's findings imply that perceived job insecurity may be a critical factor for developing major depressive disorder, in both men and women workers.

Occupation-level automation probability is associated with psychosocial work conditions and workers' health: A multilevel study

OBJECTIVE

Work automation is increasing worldwide, and the probability of job automation has been associated with workers' adverse health outcomes. This study aimed to examine the association of occupation-level automation probability with work stress and workers' health.

METHODS

We used data from a national survey of 14,948 randomly selected general workers conducted in 2016. Job control and job demand were assessed by the Job Content Questionnaire, and working hours and job insecurity were self-reported. Health outcomes were measured according to burnout and work-related injury or disease. We derived automation probabilities for 38 occupational groups and conducted multilevel analyses to examine the associations between occupation-level automation probability and workers' safety and health after adjusting for psychosocial work conditions.

RESULTS

Participants working in jobs with a high probability of automation were more likely to have low job control, higher job insecurity, and work-related injury and disease prevalence; whereas workers in jobs with a low automation probability had higher psychological and physical demands and burnout prevalence. Furthermore, automation probability significantly predicted workers' health after adjustment for demographic characteristics and psychosocial work conditions.

CONCLUSIONS

Workers with low automation probability jobs may experience work stress other than that captured by traditional measures of job strain. Organizational approaches to improve employment security and psychosocial conditions are essential for workers' safety and health in the context of increasing job automation.

Risk factors for resignation from work after starting infertility treatment among Japanese women: Japan-Female Employment and Mental health in Assisted reproductive technology (J-FEMA) study

OBJECTIVE

To elucidate the risk factors associated with resignation from work of Japanese women undergoing infertility treatment.

METHODS

A total of 1727 female patients who attended a private fertility clinic in Japan participated in the Japan-Female Employment and Mental health in Assisted reproductive technology study. Questions related to demographic, clinical and socioeconomic characteristics were employed in the questionnaire. Out of the 1727 patients, 1075 patients who were working at the time of initiating infertility treatment and felt infertility treatment incompatible with work were included in the analysis. Risk factors for resignation were assessed by using multivariable logistic regression models.

RESULTS

Among 1075 working women who started infertility treatment, 179 (16.7%) subsequently resigned. Multivariable-adjusted ORs for resignation in those with lower educational background and infertility for ≥2 years were 1.58 (95% CI: 1.07 to 2.34) and 1.82 (95% CI: 1.15 to 2.89), respectively. The OR for resignation in non-permanent workers undergoing infertility treatment was 2.65 (95% CI: 1.61 to 4.37). While experiencing harassment in the workplace approached significance, lack of support from the company was significantly associated with resignation after starting infertility treatment, with ORs of 1.71 (95% CI: 0.98 to 2.99) and 1.91 (95% CI: 1.28 to 2.86), respectively.

CONCLUSION

One-sixth of women resigned after starting infertility treatments. It was found that factors related to education, infertility duration and work environment were significantly associated with resignation. Reducing the physical and psychological burden endured by women, for example, by increasing employer-provided support, is vitally important in balancing infertility treatment with maintenance of work life.

The Performance Implications of Job Insecurity: The Sequential Mediating Effect of Job Stress and Organizational Commitment, and the Buffering Role of Ethical Leadership

Although previous works have examined how job insecurity affects the perceptions, attitudes, and behaviors of members in an organization, those studies have not paid enough attention to the relationship between job insecurity and performance or the mediating processes in that relationship. Considering that organizational performance is a fundamental target or purpose, investigating it is greatly needed. This research examines both mediating factors and a moderator in the link between job insecurity and organizational performance by building a moderated sequential mediation model. To be specific, we hypothesize that the degree of an employee’s job stress and organizational commitment sequentially mediate the relationship between job insecurity and performance. Furthermore, ethical leadership could moderate the association between job insecurity and job stress. Using a three-wave data set gathered from 301 currently working employees in South Korea, we reveal that not only do job stress and organizational commitment sequentially mediate the job insecurity–performance link, but also that ethical leadership plays a buffering role of in the job insecurity–job stress link. Our findings suggest that the degree of job stress and organizational commitment (as mediators), as well as ethical leadership (as a moderator), function as intermediating mechanisms in the job insecurity–performance link.

Chronic Spinal Pain and Financial Worries in the US Adult Population

STUDY DESIGN

Epidemiological study based on cross-sectional data of a representative sample.

OBJECTIVE

To determine whether financial worries are associated with chronic spinal pain in the US adult population.

SUMMARY OF BACKGROUND DATA

This study used data from the US 2015 National Health Interview Survey. The sample size was 33,672 and the study population is defined as aged 18 to 85 years.

METHODS

To account for the complex sampling design, the Taylor linearized variance estimation method was used. Spinal pain was defined in two ways: chronic low back pain and neck pain, chronic low back pain and/or neck pain. Eight types of financial worries were assessed: paying monthly bills, maintaining standard of living, credit card payments, paying rent/mortgage/housing costs, medical costs for healthcare, money for retirement, medical costs of illness/accident, and paying for children's college.

RESULTS

Different types of financial worries were significantly associated with chronic spinal pain, controlling for demographic characteristics and socioeconomic status. These worries included paying monthly bills (odds ratio [OR] 2.5), maintaining standard of living (OR 2.5), credit card payments (OR 2.2), paying rent/mortgage/housing costs (OR 2.2), medical costs for healthcare (OR 2.2), money for retirement, (OR 2.3), medical costs of illness/accident (OR 2.2), and paying for children's college (OR 1.4).

CONCLUSION

This study shows that financial worries were significantly associated with chronic spinal pain. Financial worries may be important to be taken into consideration by clinicians managing patients with spinal pain. More future research is needed to explore the association between financial worries and spinal pain.

The impact of employment protection on health: Evidence from fixed-term contract workers in South Korea

In this paper, we examine the impact of increased employment protection on the self-rated health of workers. We utilize the recent labor reform in South Korea which sharply increased the employment protection level of fixed-term contract workers meeting certain criteria. By applying a difference-in-differences framework to longitudinal data, we explore the causal impact of employment protection. We find that subjective health and perceived job security improved with increased statutory employment protection. Further analysis suggests that the improvement in subjective health is less likely to be driven by improvement in working conditions or health related behaviors.

Differential effects of employment grade on the association between long working hours and problem drinking

OBJECTIVE

To examine the association between working hours and problem drinking in employees from different employment grades.

METHODS

We used data from a national survey of randomly sampled Taiwanese workers. A total score of 2 or more on the Cut down, Annoyed, Guilty, and Eye-Opener (CAGE) questionnaire was used to identify problem drinkers. Weekly working hours were categorized into five groups: <40, 40, 41-48, 49-59, and ≥60. Employees were classified into three employment grades: managers and professionals, skilled workers, and low-skilled workers. The associations between working hours and problem drinking in employees from different employment grades were examined by logistic regression models.

RESULTS

In skilled workers, problem drinking was associated with <40 and 41-48 working hours, but not with >48 working hours. In low-skilled workers, problem drinking was most strongly associated with 49-59 working hours.

CONCLUSION

The association between working hours and problem drinking was not linear and differed with employment grades.

Decent Work as Determinant of Work Engagement on Dependent Self-Employed

This article analyzes with a holistic and systematic approach the state of working conditions in self-dependent workers, as well as their effects on workers’ work engagement. For this, a distinction was made between the self-employed, non-dependent self-employed, and wage earners. The sample integrated 42,963 workers who were surveyed, of which 0.03% were dependent self-employed, 13.73% were non-dependent self-employed, and 82.32% were wage earners. The results have broadly confirmed the research purposes and they established that ensuring work engagement is the key to sustainability, growth, and success for workers.

Exploring the public-private and company size differences in employees' work characteristics and burnout: data analysis of a nationwide survey in Taiwan

Distinct differences exist between public-private sector organizations with respect to the market environment and operational objectives; furthermore, among private sector businesses, organizational structures and work conditions often vary between large- and small-sized companies. Despite these obvious structural distinctions, however, sectoral differences in employees' psychosocial risks and burnout status in national level have rarely been systematically investigated. Based on 2013 national employee survey data, 15,000 full-time employees were studied. Sector types were classified into "public," "private enterprise-large (LE)," and "private enterprise-small and medium (SME);" based on the definition of SMEs by Taiwan Ministry of Economic Affairs, and the associations of sector types with self-reported burnout status (measured by the Chinese version of Copenhagen Burnout Inventory) were examined, taking into account other work characteristics and job instability indicators. Significantly longer working hours and higher perceived job insecurity were found among private sector employees than their public sector counterparts. With further consideration of company size, greater dissatisfaction of job control and career prospect were found among SME employees than the other two sector type workers. This study explores the pattern of public-private differences in work conditions and employees' stress-related problems to have policy implications for supporting mechanism for disadvantaged workers in private sectors.

Obesity trend in the United States and economic intervention options to change it: A simulation study linking ecological epidemiology and system dynamics modeling

OBJECTIVES

To study the country-level dynamics and influences between population weight status and socio-economic distribution (employment status and family income) in the US and to project the potential impacts of socio-economic-based intervention options on obesity prevalence.

STUDY DESIGN

Ecological study and simulation.

METHODS

Using the longitudinal data from the 2001-2011 Medical Expenditure Panel Survey (N = 88,453 adults), we built and calibrated a system dynamics model (SDM) capturing the feedback loops between body weight status and socio-economic status distribution and simulated the effects of employment- and income-based intervention options.

RESULTS

The SDM-based simulation projected rising overweight/obesity prevalence in the US in the future. Improving people's income from lower to middle-income group would help control the rising prevalence, while only creating jobs for the unemployed did not show such effect.

CONCLUSIONS

Improving people from low- to middle-income levels may be effective, instead of solely improving reemployment rate, in curbing the rising obesity trend in the US adult population. This study indicates the value of the SDM as a virtual laboratory to evaluate complex distributive phenomena of the interplay between population health and economy.

Influence of changes in the Spanish labor market during the economic crisis (2007-2011) on perceived health

PURPOSE

We analyze the influence of the dramatic changes in the Spanish labor market during the crisis on the perceived health of the Spanish population.

METHODS

We use the longitudinal Living Conditions Survey database and multilevel longitudinal logistic models between 2007 and 2011, before and during the economic crisis in one of the European countries most affected by its consequences.

RESULTS

Unemployment (OR 1.75; p < 0.001), job insecurity (OR 1.38; p < 0.001), and being part of a household with severe material deprivation (OR 1.87; p = 0.004) increase the risk of having worsened perceived health. Available income, on the other hand, is a protective factor (OR 0.72; p < 0.001). Public expenditure policies have little impact on the perceived health. Labor market reforms reducing the degree of job insecurity and unemployment, together with income transfers to those at greater risk of social deprivation, can be more effective in improving the health of the population than the increase of aggregated social or health care expenditure.

CONCLUSIONS

This study provides evidence of the influence that unemployment, job insecurity, and poverty exert on the perceived health of individuals, with data collected in Spain after the onset of the financial crisis. In addition, after analyzing public social expenditure, only expenditure on FPS seems to influence self-reported health, although to a very limited degree.

Employment insecurity and employees' health in Denmark

We use register data for Denmark (IDA) merged with the Danish Work Environment Cohort Survey (1995, 2000, and 2005) to estimate the effect of perceived employment insecurity on perceived health for a sample of Danish employees. We consider two health measures from the SF-36 Health Survey Instrument: a vitality scale for general well-being and a mental health scale. We first analyse a summary measure of employment insecurity. Instrumental variables-fixed effects estimates that use firm workforce changes as a source of exogenous variation show that 1 additional dimension of insecurity causes a shift from the median to the 25th percentile in the mental health scale and to the 30th in that of energy/vitality. It also increases by about 6 percentage points the probability to develop severe mental health problems. Looking at single insecurity dimensions by naïve fixed effects, uncertainty associated with the current job is important for mental health. Employability has a sizeable relationship with health and is the only insecurity dimension that matters for the energy and vitality scale. Danish employees who fear involuntary firm internal mobility experience worse mental health.

Night shift and rotating shift in association with sleep problems, burnout and minor mental disorder in male and female employees

OBJECTIVES

Shift work is associated with adverse physical and psychological health outcomes. However, the independent health effects of night work and rotating shift on workers' sleep and mental health risks and the potential gender differences have not been fully evaluated.

METHODS

We used data from a nationwide survey of representative employees of Taiwan in 2013, consisting of 16 440 employees. Participants reported their work shift patterns 1 week prior to the survey, which were classified into the four following shift types: fixed day, rotating day, fixed night and rotating night shifts. Also obtained were self-reported sleep duration, presence of insomnia, burnout and mental disorder assessed by the Brief Symptom Rating Scale.

RESULTS

Among all shift types, workers with fixed night shifts were found to have the shortest duration of sleep, highest level of burnout score, and highest prevalence of insomnia and minor mental disorders. Gender-stratified regression analyses with adjustment of age, education and psychosocial work conditions showed that both in male and female workers, fixed night shifts were associated with greater risks for short sleep duration (<7 hours per day) and insomnia. In female workers, fixed night shifts were also associated with increased risks for burnout and mental disorders, but after adjusting for insomnia, the associations between fixed night shifts and poor mental health were no longer significant.

CONCLUSIONS

The findings of this study suggested that a fixed night shift was associated with greater risks for sleep and mental health problems, and the associations might be mediated by sleep disturbance.

Effects of Social Determinants on Chinese Immigrant Food Service Workers' Work Performance and Injuries: Mental Health as a Mediator

OBJECTIVE

The effects of social discrimination, job concerns, and social support on worker mental health and the influence of mental health on occupational health outcomes have been documented intermittently. We propose an integrated, theory-driven model to distinguish the impact of social determinants on work performance and injuries and the mediating effects of mental health problems.

METHODS

The US Chinese immigrant food service workers (N = 194) completed a multimeasure interview; we tested the integrated model using structural equation modeling.

RESULTS

Mental health problems, which were associated with decreased work performance and increased injuries, also mediated relationships between job/employment concerns and both work performance and injuries but did not mediate the influences of discrimination and social support.

CONCLUSIONS

This research reveals mechanisms by which social determinants influence immigrant worker health, pointing to complementary strategies for reducing occupational health disparities.

Globalization, Work, and Cardiovascular Disease

Cardiovascular disease (CVD), a global epidemic, is responsible for about 30% of all deaths worldwide. While mortality rates from CVD have been mostly declining in the advanced industrialized nations, CVD risk factors, including hypertension, obesity, and diabetes, have been on the increase everywhere. Researchers investigating the social causes of CVD have produced a robust body of evidence documenting the relationships between the work environment and CVD, including through the mechanisms of psychosocial work stressors. We review the empirical evidence linking work, psychosocial stressors, and CVD. These work stressors can produce chronic biologic arousal and promote unhealthy behaviors and thus, increased CVD risk. We offer a theoretical model that illustrates how economic globalization influences the labor market and work organization in high-income countries, which, in turn, exacerbates job characteristics, such as demands, low job control, effort-reward imbalance, job insecurity, and long work hours. There is also a growing interest in “upstream” factors among work stress researchers, including precarious employment, downsizing/restructuring, privatization, and lean production. We conclude with suggestions for future epidemiologic research on the role of work in the development of CVD, as well as policy recommendations for prevention of work-related CVD.

Reliability and Validity of Job Content Questionnaire in Chinese Petrochemical Employees

To evaluate psychometric properties the Chinese (mainland) version of the 30-item Job Content Questionnaire was administered to 889 employees in 4 industries of PetroChina. A retest at 3 months with 296 randomly chosen employees showed reliabilities ranged from .76 to .93. Cronbach coefficients alpha for the 8 dimensions ranged from .43 to .88, indicating that the Job Insecurity subscale had low internal consistency. Exploratory factor analysis showed 8 meaningful factors corresponding to the 8 theoretical dimensions of this questionnaire. This version has variable a but suitable retest to be a reliable and valid measure of job strain, applicable to the Chinese industrial working population of PetroChina.

Low Back Pain Prevalence and Related Workplace Psychosocial Risk Factors: A Study Using Data From the 2010 National Health Interview Survey

OBJECTIVES

The objectives of this study were to estimate prevalence of low back pain, to investigate associations between low back pain and a set of emerging workplace risk factors, and to identify worker groups with an increased vulnerability for low back pain in the United States.

METHODS

The data used for this cross-sectional study came from the 2010 National Health Interview Survey, which was designed to collect data on health conditions and related risk factors from the US civilian population. The variance estimation method was used to compute weighted data for prevalence of low back pain. Multivariable logistic regression analyses stratified by sex and age were performed to determine the odds ratios (ORs) and the 95% confidence interval (CI) for low back pain. The examined work-related psychosocial risk factors included work-family imbalance, exposure to a hostile work environment, and job insecurity. Work hours, occupation, and other work organizational factors (nonstandard work arrangements and alternative shifts) were also examined.

RESULTS

The prevalence of self-reported low back pain in the previous 3 months among workers in the United States was 25.7% in 2010. Female or older workers were at increased risk of experiencing low back pain. We found significant associations between low back pain and a set of psychosocial factors, including work-family imbalance (OR 1.27, CI 1.15-1.41), exposure to hostile work (OR 1.39, CI 1.25-1.55), and job insecurity (OR 1.44, CI 1.24-1.67), while controlling for demographic characteristics and other health-related factors. Older workers who had nonstandard work arrangements were more likely to report low back pain. Women who worked 41 to 45 hours per week and younger workers who worked >60 hours per week had an increased risk for low back pain. Workers from several occupation groups, including male health care practitioners, female and younger health care support workers, and female farming, fishing, and forestry workers, had an increased risk of low back pain.

CONCLUSIONS

This study linked low back pain to work-family imbalance, exposure to a hostile work environment, job insecurity, long work hours, and certain occupation groups. These factors should be considered by employers, policymakers, and health care practitioners who are concerned about the impact of low back pain in workers.

Gender differences in the use of alcohol and prescription drugs in relation to job insecurity. Testing a model of mediating factors

BACKGROUND

The results of several studies suggest that economy-related stressors are less distressing for women compared with men. This study proposed to examine the relationship of perceived job insecurity with the use of licit drugs using a theoretical model that considered antecedents and mediators of this association, in order to identify differences between working men and women.

METHODS

Using information from the Catalan Health Survey (2010-2014), we selected working individuals aged 16-64 who were primary providers of household income (N=5315). The outcomes were two measures of alcohol consumption (heavy drinking and binge drinking) and the use of hypnotics/sedatives. As antecedents of the exposure to job insecurity we considered the type of contractual relationship and occupational class. The mediating factors were poor mental health, household structure and the hours of housework per week. The theoretical model was assessed using path analysis where the moderating effect of gender was considered in all the associations.

RESULTS

No differences in the prevalence of job insecurity were found between men and women (17%). Job insecurity (Odds ratio [OR]=1.35, 95% confidence interval [CI]=1.23-1.48) and house workload (OR=1.01, 95% CI=1.00-1.02) were positively associated with poor mental health, with no significant interactions with gender. Poor mental health was significantly associated with binge drinking (OR=1.23, 95% CI=1.13-1.33) and with the use of hypnotics/sedatives (OR=1.71, 95% CI=1.53-1.91). House workload showed a direct negative association with binge drinking (OR=0.99, 95% CI=0.98-1.00), while those in households with no children were more likely to be binge drinkers, with no significant interactions with gender. An alternative model had better fitting results for heavy drinking.

CONCLUSION

No gender differences were found in the association of job insecurity with mental health nor with the use of substances among primary providers of household income, emphasising the importance of social roles when assessing differences in mental health among men and women.

Workplace psychosocial and organizational factors for neck pain in workers in the United States

BACKGROUND

Neck pain is a prevalent musculoskeletal condition among workers in the United States. This study explores a set of workplace psychosocial and organization-related factors for neck pain.

METHODS

Data used for this study come from the 2010 National Health Interview Survey which provides a representative sample of the US population. To account for the complex sampling design, the Taylor linearized variance estimation method was used. Logistic regression models were constructed to measure the associations.

RESULTS

This study demonstrated significant associations between neck pain and a set of workplace risk factors, including work-family imbalance, exposure to a hostile work environment and job insecurity, non-standard work arrangements, multiple jobs, and long work hours.

CONCLUSION

Workers with neck pain may benefit from intervention programs that address issues related to these workplace risk factors. Future studies exploring both psychosocial risk factors and physical risk factors with a longitudinal design will be important. Am. J. Ind. Med. 59:549-560, 2016. © 2016 Wiley Periodicals, Inc.

Association of Psychosocial Work Hazards With Depression and Suboptimal Health in Executive Employees

OBJECTIVES

This study aims to investigate whether psychosocial work-related hazards, measured by workplace justice and employment insecurity, are associated with depression and suboptimal health status in Taiwan's executive-level employees.

METHODS

There were 365 executives who have received a series of cardiovascular health examinations, blood sampling, and self-reported questionnaires, which included the psychosocial work-related hazards and the CES-D scale. Suboptimal health status was defined as the presence of dyslipidemia or prediabetes.

RESULTS

Executive-level employees perceived lower workplace justice and higher employment insecurity and had a significantly higher risk of depression (CES-D scores ≥16 or ≥23). However, workplace justice was identified as a significant determinant factor that was negative for dyslipidemia but protective for prediabetes.

CONCLUSION

This study supports the fact that psychosocial work-related hazards can independently contribute to the risk of developing depression, prediabetes, and dyslipemia in executives.

Employment insecurity and mental health during the economic recession: An analysis of the young adult labour force in Italy

BACKGROUND AND OBJECTIVE

A growing body of scientific literature highlights the negative consequences of employment insecurity on several life domains. This study focuses on the young adult labour force in Italy, investigating the relationship between employment insecurity and mental health and whether this has changed after years of economic downturn. It enhances understanding by addressing differences in mental health according to several employment characteristics; and by exploring the role of respondents' economic situation and educational level.

DATA AND METHODS

Data from a large-scale, nationally representative health survey are used to estimate the relationship between employment insecurity and the Mental Health Inventory (MHI), by means of multiple linear regressions.

RESULTS AND CONCLUSIONS

The study demonstrates that employment insecurity is associated with poorer mental health. Moreover, neither temporary workers nor unemployed individuals are a homogeneous group. Previous job experience is important in differentiating the mental health risks of unemployed individuals; and the effects on mental health vary according to occupational status and to the amount of time spent in a condition of insecurity. Further, the experience of financial difficulties partly explains the relationship between employment insecurity and mental health; and different mental health outcomes depend on respondents' educational level. Lastly, the risks of reporting poorer mental health were higher in 2013 than in 2005.

Does job insecurity deteriorate health?

This paper estimates the causal effect of perceived job insecurity - that is, the fear of involuntary job loss - on health in a sample of men from 22 European countries. We rely on an original instrumental variable approach on the basis of the idea that workers perceive greater job security in countries where employment is strongly protected by the law and more so if employed in industries where employment protection legislation is more binding; that is, in induastries with a higher natural rate of dismissals. Using cross-country data from the 2010 European Working Conditions Survey, we show that, when the potential endogeneity of job insecurity is not accounted for, the latter appears to deteriorate almost all health outcomes. When tackling the endogeneity issue by estimating an instrumental variable model and dealing with potential weak-instrument issues, the health-damaging effect of job insecurity is confirmed for a limited subgroup of health outcomes; namely, suffering from headaches or eyestrain and skin problems. As for other health variables, the impact of job insecurity appears to be insignificant at conventional levels.

The effect of economic insecurity on mental health: Recent evidence from Australian panel data

This paper estimates the impact of economic insecurity on the mental health of Australian adults. Taking microdata from the 2001-2011 HILDA panel survey, we develop a conceptually diverse set of insecurity measures and explore their relationships with the SF-36 mental health index. By using fixed effects models that control for unobservable heterogeneity we produce estimates that correct for endogeneity more thoroughly than previous works. Our results show that exposure to economic risks has small but consistently detrimental mental health effects. The main contribution of the paper however comes from the breadth of risks that are found to be harmful. Job insecurity, financial dissatisfaction, reductions and volatility in income, an inability to meet standard expenditures and a lack of access to emergency funds all adversely affect health. This suggests that the common element of economic insecurity (rather than idiosyncratic phenomena associated with any specific risk) is likely to be hazardous. Our preferred estimates indicate that a standard deviation shock to economic insecurity lowers an individual's mental health score by about 1.4 percentage points. If applied uniformly across the Australian population such a shock would increase the morbidity rate of mental disorders by about 1.7%.

Associations of neighborhood-level workplace violence with workers' mental distress problems: a multilevel analysis of Taiwanese employees

OBJECTIVE

Workplace violence is known to pose mental health risks. However, whether or not workplace violence in a surrounding area might further increase the risk of mental distress in workers has rarely been examined.

METHODS

The study subjects were 9,393 male and 7,716 female employees who participated in a nationwide survey in 2010. Their personal experiences of workplace violence over the past 1 year were ascertained by a standardized questionnaire. Also assessed were their psychosocial work characteristics and mental distress problems. Neighborhood-level workplace violence was computed based on aggregated data at the county level and was categorized into low-, medium-, and high-level categories. Multilevel logistic regression models were constructed to examine the associations between neighborhood-level workplace violence and individual-level mental distress problems, with adjustment of individual-level experience of workplace violence.

FINDINGS

The neighborhood-level prevalence of workplace violence ranged from 4.7 to 14.7% in men and from 6.4 to 14.8% in women across 22 counties. As compared with those who live in counties of the lowest tertile of workplace violence, female workers who lived in counties of the highest tertile of workplace violence had a 1.72-fold increased risk for mental distress problems after controlling for individual experience of workplace violence and other psychosocial work characteristics.

CONCLUSION

Neighborhood-level workplace violence was associated with poor mental health in female workers. Preventative strategies targeting workplace violence should pay attention to neighborhood factors and gender-specific effects that might influence societal tolerance of abusive work practices and workers' vulnerability to mental health impacts of workplace violence.

Psychosocial job characteristics, wealth, and culture: differential effects on mental health in the UK and Thailand

BACKGROUND

Most research on the influence of psychosocial job characteristics on health status has been conducted within affluent Western economies. This research addresses the same topic in a middle-income Southeast Asian country, enabling comparison with a Western benchmark.

METHODS

We analysed and compared the Health Survey for England conducted in 2010 and the Thai Cohort Study data at 2005 baseline for workers aged 35-45 years. Multivariate logistic regression was used to assess relationships between psychosocial job characteristics and health, measured as Adjusted Odd Ratios (AOR), controlling for potential covariates in final analyses.

RESULTS

In both UK and Thai working adults, psychological distress was associated with job insecurity (AOR 2.58 and 2.32, respectively), inadequate coping with job demands (AOR 2.57 and 2.42), and low support by employers (AOR 1.93 and 1.84). Job autonomy was associated with psychological distress in the UK samples (AOR 2.61) but no relationship was found among Thais after adjusting for covariates (AOR 0.99). Low job security, inability to cope with job demands, and low employer support were associated with psychological distress both among Thai and UK workers.

CONCLUSIONS

Job autonomy was an important part of a healthy work environment in Western cultures, but not in Thailand. This finding could reflect cultural differences with Thais less troubled by individualistic expression at work. Our study also highlights the implications for relevant workplace laws and regulations to minimise the adverse job effects. These public health strategies would promote mental health and wellbeing in the population.

Policy Perspectives on Occupational Stress

Occupational stress is a major physical and mental hazard for many workers and has been found to contribute to cardiovascular disease, musculoskeletal disorders, mood disturbances, workplace injuries, and mental health problems. Health care utilization related to these physical and mental health problems costs employers billions of dollars annually. To combat this problem, employers should adopt a preventive approach and institute organizational and administrative changes that require the participation of both management and workers. This article reviews policies that could impact the quality of work life and influence organizational changes needed to achieve occupational health and safety. Occupational health nurses play a vital role in designing and implementing policies to improve work environments and reduce occupational stress.

Working hours, sleep duration and the risk of acute coronary heart disease: a case-control study of middle-aged men in Taiwan

BACKGROUND

This study aimed to examine whether long working hours and short sleep duration were associated with an increased risk of acute myocardial infarction (AMI) or severe coronary heart diseases (SCHD), independent of established psychosocial work-related factors.

METHODS

A case-control study was conducted. Cases were 322 men, aged <60 years and economically active, who were admitted to hospital with a first diagnosed AMI or SCHD during 2008-2011, of whom 134 were confirmed AMI and the other 188 were angiography-confirmed SCHD. Controls were 644 men who were drawn from a national survey and were matched to the cases on age, education and area of residence. Odds ratios of total CHD and confirmed AMI in relation to average weekly working hours and daily hours of sleep were calculated.

RESULTS

Men with average working hours longer than 60 h/week were found to have significantly increased risks for total CHD (OR=2.2) as compared to those with weekly working hours in 40-48 h, and those with daily hours of sleep fewer than 6 h were found to have increased risks for CHD (OR=3.0) as compared to those with sleeping hours in 6-9 h. Restriction to confirmed AMI yielded a greater risk and these associations remained consistent with adjustment of smoking status, body mass index and psychosocial work factors including job demands, job control, workplace justice, job insecurity and shift work.

CONCLUSION

The results support the hypothesis that long working hours and short sleep duration contribute independently to the risk of cardiovascular diseases in men.

Association between work-related health problems and job insecurity in permanent and temporary employees

OBJECTIVES

This research was conducted with an aim of determining the correlation between job insecurity and an employee's work-related health problems among permanent and temporary workers.

METHODS

Using the data from the First Korean Working Conditions Survey conducted in 2006, a total of 7,071 workers, excluding employers and the self-employed, were analyzed. Work-related health problems were categorized as backache, headache, abdominal pain, muscular pain, stress, fatigue, insomnia, anxiety or depression. Each problem was then analyzed for its relationship to job insecurity through logistic regression analysis.

RESULTS

Among the 7,071 workers, 5,294 (74.9%) were permanent workers and 1,777 (25.1%) were temporary workers. For the permanent workers, presence of high or moderate job insecurity appeared more closely linked to backache, headache, abdominal pain, muscular pain, stress, fatigue, insomnia, anxiety, and depression compared to absence of job insecurity. However, for the temporary workers, only depression appeared to be associated with the presence of high job insecurity.

CONCLUSION

The study showed that the presence of job insecurity is correlated with work-related health problems. The deleterious effects of job insecurity appeared to be stronger in permanent than temporary workers. Additional research should investigate ways to effectively reduce job insecurity.
