From the perspective of resource conservation theory, this study selected 568 enterprise employees as subjects and conducted data collection using a random sampling method to explore the relationship between job insecurity and safe behaviours as well as the role of insomnia and job engagement in this relationship. The results show that (1) job insecurity is negatively correlated with safety behaviour, (2) insomnia mediates the relationship between job insecurity and safety behaviour, (3) work engagement plays a mediating role in the relationship between job insecurity and safety behaviour, and (4) insomnia and work engagement play a serial mediating role in the relationship between job insecurity and safety behaviour.

Objectives: To explore the relationship between sleep pattern (morningnesseveningness) and depression in Chinese shift workers ("Three Shifts" workers), and to examine whether emotional exhaustion plays a mediating role in this relationship. Study Design: We examined the impact of sleep pattern on the depression of three shifts workers, focusing on the mediating effect of emotional exhaustion. Methods: A total of 1303 shift workers in the north and south of China were invited to participate in this study using convenience sampling. They completed a questionnaire which collected information on socio-demographic variables, along with measures of sleep pattern, depression, and emotional exhaustion. Using structural equation modelling, the mediating role of emotional exhaustion in sleep pattern and depression was explored. Results: Of the three shifts workers 46.43% reported symptoms of depression; 27.84% identified as morning types while only 6.56% were evening types, with the remaining 65.60% falling into the intermediate category. There was a negative correlation between sleep pattern and depression, and between sleep pattern and emotional exhaustion, but a positive correlation between emotional exhaustion and depression. As predicted, emotional exhaustion played a mediating role in the relationship between sleep pattern and depression. Conclusions: Having an evening sleep pattern was a risk factor for depression in three shifts workers; however, emotional exhaustion mediated the relationship between sleep pattern and depression. This finding may inform interventions aimed at reducing the level of depression within three shifts staff.

Leadership behavior has an impact on the behavior of employees. Previous studies have mainly studied the impact of positive leadership behaviors on employees’ behaviors, but there is an absence of research on the impact of negative leadership behaviours (abusive supervision) on safety behaviours (including safety participation and safety compliance). In this study, 599 front-line employees in the petrochemical industry were selected as subjects. Abusive supervision, safety behaviour, safety motivation and a conscientiousness questionnaire were used as measurements to explore the relationship between abusive supervision and employee safety behaviors, and to further explore the roles of safety motivation, conscientiousness and the relationship between them. This study found that abusive supervision is negatively related to employee safety behaviours (safety compliance and safety participation); that safety motivation plays a mediating role in the relationship between abusive supervision and employees’ safety behavior; and that conscientiousness moderates the role of safety motivation between the relationship of abusive supervision and employees’ safety behaviour. With a higher level of conscientiousness, the indirect relationship between abusive supervision and employee safety behaviours is weaker. Finally, we discuss the theoretical and practical significance of these findings for abusive supervision and the management of safety behaviours.

From the perspective of social information processing theory and social identity theory, 1,267 employees were selected as the subjects, and the data were statistically analyzed by using Mplus8.0 and SPSS25.0 to explore the relationship between positive workplace gossip and job satisfaction and the role of job insecurity and organizational identity in this relationship. The results showed that there was a significant positive correlation between positive workplace gossip and job satisfaction. Furthermore, job insecurity and organizational identity independently mediated the relationship between positive workplace gossip and employee job satisfaction. In addition, job insecurity and organizational identity played a serial mediating role in the relationship between positive workplace gossip and job satisfaction. The results of the study shed light on how job insecurity and organizational identity were associated with the process of the positive workplace gossip-job satisfaction relationship. Based on the findings, implications and avenues for future research were discussed.
