Change is inevitable in groups, and in some cases necessary for survival. Yet, at the same time, teams often resist the disruption and conflict that accompanies change, especially those involving members and practices. In this chapter, we present a line of research on team receptivity to newcomers, or the willingness of groups to adopt the newcomers’ unique contributions. We draw on conflict theories to develop a conceptual model outlining when teams experience minimal conflict or disruption due to the presence of a newcomer and accept the unique insights of this member instead. This conceptual model informs organizations on how to deal productively with conflict arising from membership change in teams.
