The associations between workplace bullying, salivary cortisol, and long-term sickness absence: a longitudinal study

Bidirectional associations between workplace bullying and sickness absence due to common mental disorders - a propensity-score matched cohort study

BACKGROUND

The link between workplace bullying and poor mental health is well-known. However, little is known about the prospective and potentially reciprocal association between workplace bullying and mental health-related sickness absence. This 2-year prospective study examined bidirectional associations between exposure to workplace bullying and sickness absence due to common mental disorders (SA-CMD) while controlling for confounding factors from both work and private life.

METHODS

The study was based on propensity score-matched samples (N = 3216 and N = 552) from the Swedish Longitudinal Occupational Survey of Health, using surveys from years 2012, 2014 and 2016. Self-reported exposure to workplace bullying was linked to registry-based information regarding medically certified SA-CMD (≥ 14 consecutive days). The associations were examined by means of Cox proportional hazards regression and via conditional logistic regression analysis. Hazard ratios and odds ratios with 95% confidence intervals were estimated.

RESULTS

Exposure to workplace bullying was associated with an increased risk of incident SA-CMD (HR: 1.3, 95% CI: 1.0-1.8), after accounting for the influence of job demands, decision authority, previous SA-CMD, as well as other sociodemographic covariates. However, we found no statistically significant association between SA-CMD and subsequent workplace bullying (OR 1.2, 95% CI 0.7-1.9).

CONCLUSIONS

The results support an association between self-reported workplace bullying and SA-CMD, independent of other sociodemographic factors and workplace stressors. Preventing workplace bullying could alleviate a share of the individual and societal burden caused by SA globally.

Is there a bidirectional relationship between workplace bullying and the risk of sickness absence? Systematic review and meta-analysis of prospective studies

Exposure to workplace bullying increases the risk of sickness absence. However, the extent and direction of this relationship for different follow-up lengths are not well established. To provide evidence regarding the direction and extent of the relationship between workplace bullying and different durations of sickness absence. We searched nine databases from their inception to 29 November 2022. Multiple independent observers screened the literature, extracted the data and used the Risk Of Bias In Non-randomised Studies of Exposure to assess the methodological quality. The overall effect sizes of odds ratio, relative risk, hazard ratio and 95% confidence intervals were calculated. Our meta-analysis demonstrated a 26% increased risk of sick leave among workers exposed to workplace bullying for all follow-up lengths (95% CI 1.18 to 1.35), even after adjusting for confounding factors. Moreover, we found a significant association between long-term sickness absence and a higher likelihood of subsequent exposure to workplace bullying, with a pooled OR of 1.63 (95% CI 1.21 to 2.04). Our study established a bidirectional relationship between workplace bullying and long-term sickness absence, highlighting that it increases the risk of sickness absence at different follow-up lengths among employees who have been bullied. Hence, organisations should be mindful of workers who resume work after prolonged absences due to illness and adopt appropriate management strategies to prevent workplace bullying.

Workplace incivility as a risk factor for workplace bullying and psychological well-being: a longitudinal study of targets and bystanders in a sample of swedish engineers

BACKGROUND

The aim of the present study is to explore whether (experienced and witnessed) workplace incivility is a risk factor for (experienced and witnessed) workplace bullying. An additional aim is to explore whether experienced workplace incivility is associated with psychological well-being above and beyond the influence of (experienced and witnessed) workplace bullying on well-being.

METHODS

A survey was distributed via e-mail to a panel of Swedish engineers. The survey was administered at three time points over one year. In total, N = 1005 engineers responded to the survey. Of these, N = 341 responded to more than one survey, providing longitudinal data. N = 111 responded to all three surveys.

RESULTS

The results showed that the likelihood of being targeted by workplace bullying was higher for those who had previously experienced incivility, even when taking previous bullying exposure into account. There was also partial support for a higher likelihood of witnessing bullying at a later time point for those that had previously witnessed incivility. Additionally, the results showed that experienced workplace incivility was negatively related to psychological well-being over time, even when controlling for previous levels of experienced and witnessed workplace bullying and well-being. However, this result was only found over one of the two time lags.

CONCLUSION

The findings of the present study suggests that workplace incivility can be a risk factor for future bullying. In addition, the findings suggest that experienced workplace incivility exerts a unique negative effect on psychological well-being, even when accounting for exposure to workplace bullying.

The last resort: Workplace bullying and the consequences of changing jobs

This study investigated the consequences of changing jobs for employees subjected to workplace bullying. First, we hypothesized that bullied employees would be more likely to change jobs than non‐bullied employees. Moreover, we hypothesized that changing jobs would result in a reduction of exposure to bullying behaviors and an alleviation of mental health problems for those bullied at baseline. The study was based on a longitudinal probability sample of the whole Swedish workforce (n = 1,095). The time lag was 18 months. The results supported all hypotheses except one. Those employees who were bullied at baseline were more likely to have changed jobs at follow‐up. Also, for the changers there was a reduction in exposure to subsequent bullying. The actual drop in exposure to bullying behaviors was significant and substantial. This gives further support for the work environment hypothesis, suggesting the work context may be a more important cause than individual characteristics. As for mental health problems, the association between bullying and subsequent anxiety was not significant for those changing jobs, suggesting that leaving a toxic workplace may reduce anxiety relatively quickly. However, depression symptoms were not affected by the change of jobs, and the association between bullying and subsequent depression was the same 18 months later. The conclusion is that changing jobs can be a useful, last resort on an individual level, improving the situation for the victim of bullying. However, it is important to note that it does not solve any underlying organizational problems and risk factors.

Associations between workplace bullying and later benefit recipiency among workers with common mental disorders

OBJECTIVE

In this study, we examined exposure to workplace bullying as a predictor of registry-based benefit recipiency among workers struggling with work participation due to common mental disorders. Further, we examined if the experience of receiving social support moderated the association between workplace bullying and benefit recipiency.

DESIGN

Secondary analyses of a randomized controlled trial.

PATIENTS

People struggling with work participation due to common mental disorders (CMD).

METHODS

Study participants (n = 1193) were from a randomized controlled trial (The At Work and Coping trial (AWaC), trial registration http://www.clinicaltrials.gov NCT01146730), and self-reported CMD as a main obstacle for work participation. Participants were at risk of sickness absence, currently on sickness absence or on long-term benefits. Benefit recipiency indicated sickness absence and/or long-term benefits (i.e., disability pension) at 6-month follow-up.

RESULTS

Of the 1193 participants, 36% reported exposure to workplace bullying. Workplace bullying was significantly associated with benefit recipiency at 6-month follow-up (OR 1.41, CI 1.11-1.79). Social support did not moderate the association between bullying and benefit recipiency.

CONCLUSIONS

The finding that workplace bullying increases the risk of later benefit recipiency suggest that bullying is a significant obstacle for work participation.

Internet use, employment performance and the health of Chinese residents

Using data from the China Labor-force Dynamics Survey 2016, this study examines the effects of Internet use on Chinese resident health and the role of employment performance in this process. The results show that Internet use had a significant positive effect on the health of Chinese residents. After addressing potential endogeneity by applying appropriate instrumental variable estimation, the main findings remain robust. Heterogeneity analysis found that the Internet is conducive to improving the health of older, less-educated and female residents, which suggests that the Internet can narrow the health gap of residents with different ages, education levels and genders. Through the analysis of the impact mechanism, it was found that although Chinese residents can improve their health by enhancing their employment performance with the help of the Internet, the mediating effect accounts for <20%, indicating that the role of employment performance in the process of improving the health of Chinese residents through Internet use is very limited. Finally, suggestions are given to promote the healthy development of China via the effects of Internet use.

Associations between developmental trajectories of peer victimization, hair cortisol, and depressive symptoms: a longitudinal study

BACKGROUND

Peer victimization has been associated with long-lasting risks for mental health. Prior research suggests that stress-related systems underlying adaptation to changing environments may be at play. To date, inconsistent findings have been reported for the hypothalamic-pituitary-adrenal (HPA) axis, and its end product cortisol. This study tested whether peer victimization was associated with hair cortisol concentrations (HCC), and whether this association varied according to sex, timing, and changes in exposure. We also examined whether peer victimization differentially predicted depressive symptoms according to HCC.

METHODS

The sample comprised 556 adolescents (42.0%; 231 males) who provided hair for cortisol measurement at 17 years of age. Peer victimization was reported at seven occasions between the ages of 6 and 15 years.

RESULTS

Peer victimization was nonlinearly associated with HCC for boys only, whereas changes in peer victimization were related to HCC for boys and girls. Peer victimization predicted more depressive symptoms for all participants, except those with lower HCC.

CONCLUSIONS

Our findings provide further support for persistent dysregulation of the HPA axis following exposure to chronic adversity, of which the expression may change according to sex and the severity of victimization.

Labour market affiliation among non-bullied colleagues at work units with reported bullying

AIM

This study investigates if non-bullied employees in Work units (WUs) where bullying occur, are more prone to leave the WUs than employees in WUs with no bullying, and if the prevalence of workplace bullying had an impact on leaving the WUs. Leaving the workplace was defined by unemployment or change of workplace at follow-up.

METHODS

We had data from 8326 Danish public health invited employees from 302 WUs. Of these 3036 responded to a questionnaire on working conditions and health in 2007. WUs were classified into three categories of WUs: (1) no bullying (0% bullied), (2) moderate prevalence of bullying (< 10% bullied), and (3) high prevalence of bullying (≥ 10% bullied). Bullied respondents were used to classify the WUs and excluded in the analyses.

RESULTS

We found odds ratios (ORs) for unemployment 1 year later of 1.27 [95% CI 0.69-2.37] in WUs with moderate prevalence of bullying and 1.38 [95% CI 0.85-2.23] among employed in WUs with high prevalence of bullying, adjusted for size of WUs, age, sex, and job category. For turnover 1 year later the ORs were 1.27 [95% CI 0.78-2.15] and 1.46 [95% CI 0.99-2.15] in WUs with moderate and high prevalence of bullying, respectively.

CONCLUSION

We did not find that non-bullied employees leave the WUs with moderate and high prevalence of bullying more than employees in WUs with no bullying behaviour 1 year later. Leaving the workplace tended to be higher among employees in WUs with high prevalence of bullying compared to no and moderate bullying.

Workplace bullying, mental distress, and sickness absence: the protective role of social support

PURPOSE

This study examined the protective effects of supervisor, colleague, and non-work-related social support on the associations between workplace bullying, mental distress, and medically certified sickness absence. We hypothesized that social support moderated the direct association between workplace bullying and mental distress as well as the indirect association between bullying and sickness absence through mental distress. We also hypothesized that the protective effects of social support were stronger among women than among men.

METHODS

A sample of 10,627 employees was recruited from 96 Norwegian organizations. Workplace bullying, mental distress, and social support were assessed through a questionnaire survey and responses were linked to official registry data on medically certified sickness absence for the year following the survey assessment.

RESULTS

The results showed that all three investigated sources of social support moderated the direct association between workplace bullying and mental distress. Supervisor support moderated the indirect association between workplace bullying and sickness absence through mental distress among both male and female respondents, whereas colleague support moderated this indirect association among women only. Non-work-related support had no protective effect on the indirect association.

CONCLUSIONS

The findings suggest that social support, and especially supervisor support, is beneficial with regard to reducing the negative impact of workplace bullying on health and work ability of those exposed. Organizations should, therefore, include social support in interventions targeting bullying.

Workplace Bullying and Medically Certified Sickness Absence: Direction of Associations and the Moderating Role of Leader Behavior

The aim of this study was to determine (1) associations between workplace bullying and subsequent risk and duration of medically certified sickness absence, (2) whether employees’ perceptions of supportive, fair, and empowering leader behavior moderate the association between bullying and absence, and (3) whether prior sickness absence increases the risk of being a new victim of bullying. Altogether, 10,691 employees were recruited from 96 Norwegian organizations in the period 2004–2014. The study design was prospective with workplace bullying and leader behavior measured at baseline and then linked to official registry data on medically certified sickness absence for the year following the survey assessment. For analyses of reverse associations, exposure to bullying was reassessed in a follow-up survey after 24 months. The findings showed that workplace bullying was significantly associated with risk (risk ratio = 1.23; 95% CI = 1.13–1.34), but not duration (incidence rate ratio = 1.05; 95% CI = 0.89–1.25) of medically certified sickness absence after adjusting for age, gender, and supportive, fair, and empowering leader behavior. None of the indicators of leader behavior moderated the association between bullying and sickness absence (both risk and duration). Adjusting for baseline bullying, age, and gender, prior long-term sickness absence (>21 days) was associated with increased risk of being a new victim of bullying at follow-up (odds ratio = 1.86; 95% CI = 1.28–2.72). Effective interventions toward workplace bullying may be beneficial with regard to reducing sickness absence rates. Organizations should be aware that long-term sickness absence might be a social stigma as sick-listed employees have an increased risk of being bullied when they return to work.

Effects of workplace bullying on Chinese children's health, behaviours and school adjustment via parenting: study protocol for a longitudinal study

BACKGROUND

Bullying in the workplace is a serious public health issue. As a chronic work stress, workplace bullying places the victims' physical and mental health at risk which, in extreme cases, may lead to suicidal ideation. The high prevalence rate of workplace bullying has been reported and documented globally. However, a major limitation of the existing literature is that studies essentially focus on the consequences of workplace bullying on victims, including the psychological, physiological and socioeconomic impacts, and on the factors causing workplace bullying, but research on the impact of workplace bullying on the victims' families is lacking. It is however evident that the consequences of workplace bullying have a spillover effect on the victims' family members. Since many victims have children and given that children are particularly vulnerable to a negative family environment, examining the impacts of the type of parental stress induced by workplace bullying on children's health including physical and psychological health (depression and self-esteem), externalizing problem behaviors (aggression, lying, disrespect) and school adjustment (academic performance and school conduct) is urgently needed. The overall aim of this study is to examine how health, externalizing problem behaviors and school adjustment of children whose parents are victims of workplace bullying may be associated with the impact that workplace bullying has on parenting practices.

METHODS

It is a longitudinal study. Quantitative data will be collected from multi-informants, including currently employed Chinese parents, their children aged between 6 and 12 years old, and their class teachers at two time points, separated by a 1-year interval. One primary school will be recruited from each district of Hong Kong including participants with different socioeconomic backgrounds. At least 837 dyads (parents and children) from 18 primary schools will join the study.

DISCUSSION

Workplace bullying not only affects victims but can also be harmful to their families as it alters the victims temper in the family environment. Results will be informative for the government and corporations to make concerted efforts and find strategies to prevent workplace bullying and to heighten the awareness of the importance of promoting safe and respectful workplaces for workers.
