The Voice Link: A Moderated Mediation Model of How Ethical Leadership Affects Individual Task Performance

This study empirically examines the proposition that ethical leadership may affect individuals’ task performance through enhancing employees’ promotive voice. Our theoretical model was tested using data collected from employees and supervisors in a high-tech company located in South China. Analyses of multisource three-wave data from 37 team supervisors and 176 employees showed that ethical leadership could significantly affect individuals’ task performance through promotive voice. Further, it was found that the relationship between ethical leadership and promotive voice was moderated by leader–leader exchange. Specifically, ethical leadership may significantly enhance employees’ promotive voice when leader–leader exchange is low. The theoretical and practical implications of these findings are discussed.
