Abstract

This article examines the win rates of specific unions in grievance arbitration cases. It is hypothesizd that no significant difference in the win rates exists between unions and therefore they are perfect substitutes for one another in grievance representation. The data used for testing the hypothesis are from standard published sources. The empirical results suggest that most unions are close substitutes; however, some unions have win rates greater than the average and some win significantly lower proportions of their cases. From the evidence it appears unions may not be close substitutes (exchangeable for one another). Therefore we reject the hypothesis.
