Recent scholars have established that knowledge hiding does not equate to the lack of knowledge sharing. Due to a scarcity of papers on knowledge hiding, this paper aims to understand the mechanisms through which ethical leadership influences knowledge hiding based on social learning theory and social cognitive theory.

The field study involves 243 employees from public listed companies in Malaysia. Partial least square structural equation modelling is used to test the hypothesised relationships.

The results indicate that moral disengagement mediates the relationship between ethical leadership and knowledge hiding. Furthermore, organisational commitment moderates the negative relationship between ethical leadership and knowledge hiding, such that the negative relationship is stronger when organisational commitment is high.

This study is the first to investigate the influence of ethical leadership on knowledge hiding through the mediating effect of moral disengagement. Moreover, organisational commitment is an important boundary condition for the relationship between ethical leadership and knowledge hiding. The implications for practice and future research are also discussed.

Cyberloafing (employees' non-work-related online activities at work) has become a common workplace problem for many organizations. Research investigating the underlying mechanisms and boundary conditions under which abusive supervision influences cyberloafing remains largely underdeveloped. Drawing from social exchange theory and conservation of resources theory, we developed a moderated-mediation model in which emotional exhaustion was theorized as a unique mechanism underlining why employees are more likely to engage in cyberloafing under the supervision of abusive leaders. In addition, we proposed that organizational commitment to be a relevant boundary condition to influence such a relationship.

We collected 255 data from employees working in public listed companies in Malaysia and used partial least squares structural equation modeling (PLS-SEM) to analyze the data.

The results showed that the influence of abusive supervision on cyberloafing through emotional exhaustion is only significant when organizational commitment is low.

This study constructed a moderated-mediation model by introducing the potential mediating effect of emotional exhaustion and the moderating effect of organizational commitment to reveal the mechanism through which abusive supervision related to cyberloafing.
