This study investigates the influence of leadership on followers' identification with their work group. Adopting a qualitative research approach, it takes on the followers' perspective for inductively deriving leadership behaviors that pertain to the development of team identification. Based on in-depth data from members of seven teams in the context of UN peacebuilding operations, four aggregate leadership dimensions can be identified that are conducive to members' team identification: providing guidance, encouraging involvement, role modeling, and administering teamwork. Accordingly, this study adds to the exploration of leadership behaviors relevant for team identification that have not been considered by extant research. The results may lay the foundations for future investigations on complementary effects of different leadership behaviors for fostering followers' identification with their work group.
