Summary The current research explores supervisor-level antecedents of abusive supervision in the workplace. Specifically, this study introduces affective events theory to the abusive supervision literature to suggest that supervisor role overload, a work-related event, leads to supervisor frustration. As an intense negative emotional reaction, frustration, in turn, triggers supervisors to exhibit abusive behaviors in the workplace. Supervisor personality traits—namely, neuroticism, conscientiousness, and agreeableness—are also posited to moderate these hypothesized relationships. Specifically, neuroticism is expected to moderate the relationship between role overload and frustration while conscientiousness and agreeableness are expected to moderate the relationship between frustration and abusive supervision. Ultimately, we propose and examine a moderated-mediation model. Multisource field data demonstrate general support for the hypothesized relationships. We conclude with theoretical and practical implications as well as future research avenues. Copyright © 2016 John Wiley & Sons, Ltd.
