To further explicate the relationship between ethical leadership and unethical employee behavior, we adopted a role-based perspective and introduced the concept of perceived ethical role breadth. That is, we explored the impact that leaders’ actions and voice behaviors have on in-role versus extra-role perceptions of employees as they relate to ethical behavior and the impact, in turn, on unethical behavior. In a field study involving 394 employees and 68 supervisors and a randomized experiment conducted with 121 working professionals we find that, as predicted, leaders’ behaviors and voice have a significant influence on perceived ethical role breadth and that these role breadth perceptions impact unethical behavior. Based on our empirical findings, we describe the implications, limitations, and future directions relevant to this study.10aManagement1 aPaterson, Ted1 aHuang, Lei  u/biblio/am-i-expected-be-ethical-role-definition-perspective-ethical-leadership-and-unethical
