Work from Home during the COVID-19 Pandemic-The Impact on Employees' Self-Assessed Job Performance

Determinants of improving the relationship between corporate culture and work performance: Illusion or reality of serial mediation of leadership and work engagement in a crisis period?

The disease COVID-19 has had an impact on the lives of all people in the world. It also had a great impact on the world economies themselves. There are several scientific publications on the impact of the COVID-19 disease on the work performance of employees, while researchers have focused on less traditional factors such as corporate culture, leadership, or work engagement as well. Corporate culture influences the shared values or behavior of employees at the workplace and creates an environment in which employees work. Through leadership, managers should be able to motivate their employees and thereby ensure their better work performance. It can be assumed that if employees are more engaged, their work performance will be higher. The main goal of the paper is to examine whether corporate culture has an impact on the work performance of employees through the mediators of leadership and work engagement. The data necessary for the goal set in this way were obtained through a questionnaire survey, which was attended by 489 respondents during the year 2022. After the data reliability analysis, by using serial mediation with two mediators, the influence of corporate culture on work performance was verified independently, but also through the mediators of leadership and work engagement. Based on the results, it can be claimed that individual factors have a significant impact on work performance, while the influence of corporate culture mediated by leadership and work engagement was also confirmed. The influence of corporate culture, mediated only by leadership, and the independent influence of corporate culture through work engagement on work performance were also confirmed.

How Do COVID-19 Risk, Life-Safety Risk, Job Insecurity, and Work-Family Conflict Affect Miner Performance? Health-Anxiety and Job-Anxiety Perspectives

The coronavirus pandemic (COVID-19) has created challenging working conditions in coal-production activities. In addition to the massive loss of resources for miners, it has had a devastating impact on these individuals' mental health. Based on the conservation of resources (COR) theory and a resource-loss perspective, this study examined the impact of COVID-19 risk, life-safety risk, perceived job insecurity, and work-family conflict on miners' job performance. Moreover, this study investigated the mediating role of job anxiety (JA) and health anxiety (HA). The study data were collected through online structured questionnaires disseminated to 629 employees working in a coal mine in China. The data analysis and hypothesis generation were conducted using the structural equation modeling (partial least squares) method. The results demonstrated that the perception of COVID-19 risk, life-safety risk, job insecurity, and work-family conflict negatively and significantly impacted miners' job performance. In addition, JA and HA negatively mediated the relationships between the perception of COVID-19 risk, life-safety risk, perceived job insecurity, work-family conflict, and job performance. The findings of this study can give coal-mining companies and their staff useful insights into how to minimize the pandemic's effects on their operations.
