The purpose of this paper is to examine the association between abusive supervision and knowledge hiding behaviors. The authors further investigate how abusive supervision is linked with knowledge hiding behaviors, and why some subordinates, unlike others, tend to engage in more knowledge hiding behaviors in response to abusive supervision. The authors propose that interpersonal justice mediates the relationship between abusive supervision and knowledge hiding behaviors, and that Islamic work ethics (IWE) weaken the hypothesized relationship between abusive supervision and knowledge hiding behaviors.
