<p>Research has shifted from examining the harmful effects of workplace deviance to focusing on preventing or mitigating it through a perpetrator-centered perspective. However, findings on whether perpetrators subsequently engage in reparative behaviors remain inconsistent. We rely on moral cleansing theory to postulate that deviant peer pressure is a significant contextual factor in determining perpetrators’ future moral choices. We propose that when deviant peer pressure is low, employees are more likely to experience guilt after perpetrating workplace deviance, thereby inducing their helping behaviors. Simultaneously, employees would also perceive a loss of moral credits, resulting in reduced engagement in workplace deviance. Empirical evidence from an experiment and a three-wave field study involving multiple sources supports our hypotheses. These findings offer novel insights into resolving conflicting results in the workplace deviance literature and highlight the crucial role of deviant peer pressure in shaping responses to workplace deviance. We also discuss theoretical and practical implications.</p>
