Followership refers to the role that individuals play in supporting a leader within an organization, team, or group. Effective followers are described as enthusiastic, intelligent, ambitious, and self-reliant. Robert Kelley identified four main qualities of effective followers: self-management, commitment, competence, and courage. Kelley's model of follower behavior categorizes followers as sheep (passive and dependent), yes people (active but dependent), survivors (passive but independent), alienated followers (passive and independent), and effective followers (active and independent).
