This paper's goal is to develop an appropriate systematic literature review of the research that has investigated how ethical leadership affects employees' performance within an enterprise. The growth of multinational corporations provides a new dimension to the investigation of leadership that takes into account the effect of diverse country cultures. This systematic literature review analyzed publications and articles published within the last decade (2009- 2020). Based on the overall research of the 19 analyzed studies top managers, leaders, and supervisors are supposed to set a good example for their team members and employees by modeling ethical behavior. The effectiveness of top managers and leaders on employees and their performance has been thoroughly investigated in many research. All hypotheses were supported by the data collected from 19 papers, which showed that ethical leadership improves employees' in-role job performance. These findings have important research and practical consequences. Additionally, since ethical leadership is seen to be essential in enhancing the accepted business strategy in the achievement of organizations’ objectives and goals, this research will concentrate on the effects of an ethical leadership style on the performance of employees.
