Blaming leaders for team relationship conflict? The roles of leader-member exchange differentiation and ethical leadership

Abstract

Purpose – The purpose of this paper is to extend our understanding of the role of leaders in team relationship conflict. Leader-member exchange (LMX) differentiation was hypothesized to be positively related to team relationship conflict. Additionally, ethical leadership was hypothesized to moderate relations between LMX differentiation and team relationship conflict. Design/methodology/approach – Hypotheses were examined in a sample of 79 working teams. Data were collected via a questionnaire containing measures of LMX, team relationship conflict and ethical leadership. Findings – Hypotheses were supported by the data. LMX differentiation was positively related to team relationship conflict, and ethical leadership weakened the relationship between LMX differentiation and team relationship conflict. Originality/value – This is the first theoretical analysis and empirical study of relationships between LMX differentiation and team relationship conflict. Theoretically, by using LMX theory to account for team-level outcomes, this study extended power of LMX theory. Practically, these results suggest that leaders may be responsible for team relationship conflict.
