The present paper explores how leader prototypicality and procedural fairness connect in stimulating follower cooperation. We, first of all, argue that leader prototypicality (the extent to which a leader represents the group identity) enhances positive perceptions about the future. It does so by positively influencing perceptions of the leader's procedural fairness (at least among strongly identifying group members). Such perceptions of procedural fairness, in turn, stimulate follower cooperation. Secondly, we argue that leader prototypicality also facilitates the enactment of fair procedures by increasing the effectiveness that a procedurally fair treatment has on follower cooperation. We present an overview of very recent studies that support both arguments and conclude that group based dynamics, which determine the group prototype, have important influences on the effectiveness with which leaders can stimulate cooperation by means of procedural fairness.In our diverse and internationally oriented society it is important that teams, groups, and organisations fare well to contribute effectively to our welfare. To achieve this end, it is necessary that cooperation and withingroup relationships are coordinated in effective ways. Cooperation reflects the positive behaviours that group members display such as exerting themselves on the job and supporting the organisation or team by contributing individual effort, time, and resources to collective projects
