Embedded in higher educational settings, this study examines the relationship between abusive supervision and psychological capital and the mechanism through which abusive supervision and team member support interact to influence psychological capital with supervisor-student exchange mediating the interaction with psychological capital.

Theoretical and practical implications of these findings are discussed.

Drawing from ego depletion theory, our theoretical extension includes a serial mediation model of nightly sleep quantity and quality as predictors of abusive supervision. We argue that poor nightly sleep influences leaders to enact daily abusive behaviors via ego depletion, and these abusive behaviors ultimately result in decreased daily subordinate unit work engagement. We test this model through an experience sampling study spread over ten work days with data from both supervisors and their subordinates. Our study supports the role of the indirect …
