To the best of the author’s knowledge, this study was the first to investigate the moderating effects of sleep quantity and sleep quality on the relationships between role overload, role ambiguity, role conflict, and interpersonal conflict with job satisfaction. In doing so, it addressed a gap in the literature on organizations and provided a new direction for future research in this sphere. Leveraging the Job Demands-Resources model as a theoretical foundation, this study looked at sleep quantity and quality as personal resources capable of counteracting the negative impacts of the aforementioned job stressors on job satisfaction. Underscoring their known detrimental impact, analyses of data from 113 participants yielded statistically significant inverse effects of each job stressor on job satisfaction. Sleep quantity was then found to moderate the effect of role ambiguity on job satisfaction such that participants who slept longer were not as affected by high role ambiguity as those who got less sleep. Sleep quality moderated the effects of role overload and interpersonal conflict on job satisfaction such that higher quality of sleep offset the degree to which greater levels of these two stressors hurt job satisfaction. Recommendations are provided for how organizations can apply these findings and what direction future research studies should take.
