Leader-member exchange (LMX) is the foremost dyadic theory in the leadership literature. Whereas contemporary leadership theories, such as transformational, servant, or authentic, focus on the effects of leader behaviors on employee attitudes, motivation, and team outcomes, relational leadership theory views the dyadic relationship quality between leaders and members as the key to understanding leader effects on members, teams, and organisations. This approach views the trust- and respect-based relationships as the cornerstone of leadership.
