Servant leadership and mistreatment at the workplace: mediation of trust and moderation of ethical climate

Abstract

PurposeWith a foundation in social exchange theory, this study examines the relationship between servant leadership and three types of workplace mistreatment – bullying, incivility and ostracism – while also considering a mediating role of trust in the leader and a moderating role of the ethical climate.Design/methodology/approachThree time-lagged sets of data (N = 431) were collected among employees working in various sectors.FindingsServant leadership relates significantly to trust in the leader, as well as to workplace bullying, incivility and ostracism. In turn, trust in the leader mediates the relationship between servant leadership and all three types of workplace mistreatment. The results also indicate the presence of moderated mediation, in that the indirect effect of servant leadership on workplace mistreatment is moderated by the ethical climate.Originality/valueThis study adds to extant research by examining the mediating mechanism of trust in leaders with servant leadership and workplace mistreatment, along with interactive effects of ethical climate.
