Step-by-step explanation:
The potential for discrimination in LMX (Leader-Member Exchange) comes from leaders' openness to followers' movement into in- or out-groups. In LMX, leaders develop different relationships with their followers, with some being in the in-group and others in the out-group. Discrimination can occur when leaders show favoritism towards certain followers and exclude or marginalize others based on their placement in either group.
