Abstract

Ethical leadership encompasses the personal conduct of the leader and the leader’s expectations that followers behave ethically. Building on social learning and social exchange theory, we propose that ethical leadership interacts with coworker ethicality to predict personnel’s ethical intentions and organizational citizenship behavior. Using data collected from a large organizational sample, we use moderated regression analysis to test the main and interactive effects of ethical leadership and coworker ethicality on ethical intentions and OCB as it relates to conscientiousness, civic virtue, and altruism. Study 1 examines how ethical leadership and coworker ethicality interact to predict ethical intentions using a sample of 1,551 military personnel. Study 2 extends the results of Study 1 by examining how ethical leadership and coworker ethicality interact to predict OCB using a combined sample of 3,363 military and civilian personnel. Consistent with social learning theory, we found positive relationships between ethical leadership and coworker ethicality with ethical outcomes. Consistent with social exchange theory, we found that perceptions of ethical leadership strengthened the relationship between coworker ethicality and ethical intentions and OCB, highlighting the importance of leaders in shaping the behavior of organizational members.
