This study investigates the connection between following Islamic work ethics (IWE) and workplace deviance, and explores the role of perceived organizational politics as a mediator and the impact of incivility initiated by supervisors as a second-stage moderator. Data were collected via a two-wave survey of 205 professionals in various industries. Results show that those who adhere to IWE exhibit a negative link to workplace deviance, as they have less involvement in organizational politics. The study also finds that incivility initiated by (...) supervisors intensifies the positive relationship between perceived organizational politics and workplace deviance. Interestingly, the study shows that the effect of IWE in reducing workplace deviance through organizational politics is stronger when incivility is high. The findings offer valuable insights for organizations on the positive impact of adhering to IWE on reducing perceived organizational politics and workplace deviance. (shrink)
