In a survey-based field study of 111 permanent Finnish restaurant employees, the authors investigated intergroup relations between permanent and contingent workers. On the basis of the common in-group identity model, the authors hypothesized that the conditions of contact (supportive norms and perceived intergroup competition) would be related to common in-group identity, which in turn would be negatively related to intergroup bias. The present results indicated that perceived competition and institutional support were related to in-group bias only through their influence on the common in-group identity, as the model predicted.
