This study uses the conservation of resources theory to examine the influence of a leader's destructive behaviors by investigating how emotional exhaustion resulting from abusive supervision affects employees' knowledge-sharing behaviors. Using a moderated mediation framework, this study suggests that organizational justice moderates the positive relationship between abusive supervision and employees' emotional exhaustion and attenuates the negative indirect effect of abusive supervision on employees' knowledge-sharing behaviors. The results of this study, drawn from a sample of 202 dyads comprising full-time employees and their immediate supervisors, support most of its hypotheses. The implications and limitations of the study, as well as directions for future research, are discussed.
