In this study, we investigate the consequences of a temporary change in team composition (TCTC) as a phenomenon that is different from collective turnover. In particular, we examine the underlying characteristics of a TCTC, how such a change affects organizational performance, and which intervening resources moderate the relationship between a TCTC and team results. We conduct our study in the Italian “Serie A” top professional football/soccer league between the 1960-61 and 1991-92 seasons. Our findings suggest that TCTC negatively affects teams’ results but that team experience positively moderates the relationship between TCTC and team performance.
