6. Conclusion
The results of this study indicate that ethical leadership, either directly or indirectly, has affected deviant behavior in the workplace. Increasingly, leader’s ethical behavior could reduce deviant behavior. In this case, ethical leadership is a manifestation of honesty and credibility, concern, doing the right thing, openness of communication, personal life based on morality standards, being fair in decision making, values and ethics communicating, punishment and reward application, ethics, role modeling.
Reducing deviant behavior in the workplace can be done by realizing an ethical climate formed through conditions that prioritize the interests of the organization rather than personal interests as well as by holding and implementing ethical principles in the organization. By increasing organizational commitment, employee who are loyal and have a psychological bond on the organization are likely to have higher commitment so that the possibility of their deviant behavior is low.
Ethical leadership has not been strong enough to make a real contribution to the improvement of organizational commitment. Organizational commitment does not play a role in mediating the influence of ethical leadership on deviant behavior because ethical leadership has no significant effect on organizational commitment. Nevertheless, we found that organizational commitment has significant influence on deviant behavior in the workplace.
