Bearing the brunt: a daily diary examination of abusive supervision and the sustaining role of coworkers' support

PurposeThis study aims to examine the relationship between abusive supervision and workplace incivility using a dual theoretical framework. First, it draws on the ego depletion theory to investigate the relationship between abusive supervision and incivility by exploring the mediating role of ego depletion. Second, it integrates the job demands-resources model with the ego depletion theory to examine how perceived co-workers' support functions as a buffer in mitigating the effects of ego depletion on incivility.Design/methodology/approachThe authors tested our moderated mediation model using hierarchical linear modeling through an experience-sampling study based on data collected from a participants across five consecutive workdays.FindingsThe findings reveal employees subjected to abusive supervision are more likely to experience a depletion of self-regulatory resources. Moreover, the authors found a positive association between ego depletion and workplace incivility, suggesting that diminished self-control resulting from abusive supervision contributes to a higher likelihood of engaging in uncivil workplace behaviors. In addition, perceived coworkers' support emerged as a significant moderating factor that attenuates the indirect impact of abusive supervision on workplace incivility through ego depletion. Specifically, when perceived coworkers' support is high, the negative influence of abusive supervision on ego depletion, and subsequently, on workplace incivility, is mitigated.Originality/valueBy exploring ego depletion as the underlying mechanism and boundary conditions imposed by perceived coworker support on the relationship between abusive supervision and workplace incivility, this research contributes to a nuanced understanding of the intricate dynamics of this relationship. Based on the research findings, the authors advocate that organizations should establish and integrate support services, such as counseling and employee assistance programs, to reduce the emotional turmoil caused by abusive supervision.
