![]() The study sample consisted of 463 participants working full time in daytime white-collar positions. This study utilized moderated multiple regression to test the predictions that: (1) chronotype and early work-start times interact to affect job satisfaction and performance such that the relationship would be negative for early work-start times, then positive as start times got later (2) chronotype and early work-start times interact to affect absenteeism such that the relationship would be positive for early work-start times, then negative as start times got later and, (3) there is a partial mediating effect of sleep deprivation on these relationships. Prior research demonstrated that natural sleep-wake cycles were often misaligned with social schedules (circadian desynchrony), leading to decrements in performance, satisfaction, and attendance. This study examined the relationship of employees’ natural sleep-wake cycles (chronotypes) and work-start times with self-reports of performance, job satisfaction, and absenteeism, and the mediating role of sleep deprivation in this relationship. © 2015 The International Association of Applied Psychology. These results contribute to understanding changes in employees' fatigue and suggest that the differential effects of distress and eustress experiences at work may be important to consider in fatigue management interventions. The indicators of eustress, happiness and meaningfulness, predicted lower fatigue at both time points but not temporal changes. ![]() Multilevel modeling showed that the indicators of distress, stress and pain, predicted higher morning fatigue and stronger increases in fatigue during the workday. It was expected that within-person changes in fatigue from waking to working would be moderated by employees' experiences of stress, pain, happiness, and meaningfulness at work.ĭata on 1,195 full-time working adults were collected through the Bureau of Labor Statistics' 2010 American Time Use Study (ATUS) using a day reconstruction method to assess fatigue at two time points (morning and during work) and employees' eustress and distress experiences during work. The current study examined the influence of positive (eustress) and negative (distress) work experiences on changes in fatigue from morning to at-work. This paper addresses the call for attention to examining the mechanisms through which sleep deficit affects employee creative behavior.Īs a potential indicator of strain, fatigue is an important outcome in occupational health research. Also, the relationship between emotional exhaustion and creativity is more negative for managers than for non-managers because of managers' higher job demands.īy presenting sleep deficit-linked inhibitors of creativity at work, the authors highlight the importance of securing sufficient sleep and affective resources when designing jobs and HR practices in organizations. Specifically, when sleep-deprived, those working in a high-task-interdependence climate are likely to experience emotional exhaustion more severely than do those in a low-task-interdependence climate. Further, the study presents that higher job demands can worsen the negative effects of resource depletion on creativity at work because they further deplete resources needed for creative behaviors. Through the data, the study presents how the depletion of resource, that is, emotional exhaustion, functions as a mediating mechanism that connects sleep deficit to creativity at work. ![]() The authors conducted multilevel analysis to test the proposed hypotheses to account for the hierarchical nature of the data while simultaneously estimating the effect of predictors at different levels on individual-level outcomes and maintaining the predictors' level of analysis. The survey data were collected from 368 individuals nested in 40 teams at a call center. Within the theoretical frameworks of conservation of resources and job demands-resources (JD-R), the study aims to examine how sleep deficit could be negatively related to creativity at work by depleting critical resources of creativity.
