Although organizational research on health-related behaviors has become increasingly popular, little attention has been paid to unhealthy eating. Drawing on the self-regulation perspective, we conducted 2 daily diary studies to examine the relationships between work-related stressors, sleep quality, negative mood, and eating behaviors. Study 1 sampled 125 participants from 5 Chinese information technology companies and showed that when participants experienced higher levels of job demands in the morning, they consumed more types of unhealthy food and fewer types of healthy food in the evening. In addition, sleep quality from the previous night buffered the effect of morning job demands on evening unhealthy food consumption. Study 2 used data from 110 customer service employees from a Chinese telecommunications company and further demonstrated a positive association between morning customer mistreatment and evening overeating behaviors, as well as the buffering effect of sleep quality. Results from Study 2 also supported afternoon negative mood as a mediator linking morning customer mistreatment to evening overeating behaviors. Finally, our findings revealed that the buffering effect of sleep quality was channeled through employees' vigor in the morning, which subsequently weakened the effect of customer mistreatment on negative mood.

The teams literature suggests that team tenure improves team psychological safety climate and climate strength in a linear fashion, but the empirical findings to date have been mixed. Alternatively, theories of group formation suggest that new and longer tenured teams experience greater team psychological safety climate than moderately tenured teams. Adopting this second perspective, we used a sample of 115 research and development teams and found that team tenure had a curvilinear relationship with team psychological safety climate and climate strength. Supporting group formation theories, team psychological safety climate and climate strength were higher in new and longer tenured teams compared with moderately tenured teams. Moreover, we found a curvilinear relationship between team tenure and average team member creative performance as partially mediated by team psychological safety climate. Team psychological safety climate improved average team member task performance only when team psychological safety climate was strong. Likewise, team tenure influenced average team member task performance in a curvilinear manner via team psychological safety climate only when team psychological safety climate was strong. We discuss theoretical and practical implications and offer several directions for future research. (PsycINFO Database Record

Summary Although theory suggests that regulatory focus fluctuates within person and such fluctuations impact employee well‐being, there is little empirical investigation of such propositions. These are important research questions to address because work events may elicit within‐person fluctuations in regulatory focus, which can then affect well‐being. The primary purpose of this study is to examine specific predictors of daily regulatory focus at work and the foci's impact on employee well‐being at work and home as indicated by mood and psychosomatic complaints, respectively. We present and test an overarching theoretical framework that integrates conservation of resources theory, the cognitive‐affective processing system framework, and regulatory focus theory to delineate why and when work events affect regulatory focus and how the foci affect well‐being. Consistent with our expectations, we found that positive work events positively predicted daily promotion focus, but this effect was weaker when employees had high‐quality relationships with leaders. Furthermore, daily regulatory focus was associated with employee well‐being (mood and psychosomatic complaints) such that (i) promotion focus improved well‐being; (ii) prevention focus reduced well‐being; and (iii) the effects of promotion focus on well‐being were strongest when prevention focus was low. We discuss theoretical and practical implications and offer directions for future research. Copyright © 2016 John Wiley & Sons, Ltd.

Although helping behavior at work is widely studied, little is known about the processes via which help providers increase or decrease their helping behavior. In the current research, we integrated both enrichment-based and depletion-based perspectives on helping with Kahn’s psychological conditions for engagement to offer more comprehensive understanding of how helping behavior may change. Specifically, based on Kahn’s model, we simultaneously consider the beneficial effects of helping on help providers’ psychological meaningfulness and psychological safety along with the detrimental effects of helping on help providers’ psychological resource availability in order to uncover the differential processes through which helping behavior may change. To test our theoretical model, we collected data from a sample of 375 employees using a three-wave time-lagged design. Supporting the enrichment-based perspective, our results demonstrated that employees’ helping behavior was positively related to increases in their psychological meaningfulness and psychological safety. Supporting the depletion-based perspective, results showed that helping behavior was also positively related to increases in emotional exhaustion, an indicator of psychological resource availability. Whereas psychological meaningfulness and psychological safety were, in turn, positively related to increases in job involvement, emotional exhaustion was negatively related to increases in job involvement. Finally, job involvement was positively related to subsequent increases in employee helping behavior. We discuss the implications of our findings for both theories and practices.
