The document discusses Leader-Member Exchange Theory (LMX), which focuses on the unique relationship between a leader and each follower. LMX proposes that leaders form in-groups and out-groups among followers based on factors like competence, compatibility, and loyalty. Members of the in-group receive greater responsibilities, support, and negotiating latitude from the leader in exchange for higher performance. Those in the out-group comply with basic role requirements but have less influence and engagement with the leader. High-quality leader-member exchanges are associated with positive organizational outcomes while poor exchanges can cause alienation and low performance.
