In 2 studies, we investigated how groups with strong divisions may, paradoxically, help members to cope with injustice. We tested our theoretical predictions using a survey methodology and data from 57 (Study 1) and 36 (Study 2) workgroups across different industries. Consistent with our hypotheses, we found that group faultlines weakened the positive relationship between perceived interpersonal injustice and psychological distress. Cooperative behaviors within subgroups mediated the interactive effect of faultlines and injustice with psychological distress.
