Union loyalty antecedents: A justice perspective

Using a justice perspective, this study investigates the relationship between union instrumentality and union loyalty in terms of union ability to address both outcome-based and process-based membership concerns. The results of hierarchical regression analysis using a sample of 451 train crew members from four railroads showed that member satisfaction with outcome-based concerns (i.e., pay, time spent away from home, safety climate) did not significantly affect union loyalty, but that member satisfaction with process-based concerns (i.e., effectiveness of the grievance procedure and satisfaction with communication from national union leaders) was significantly related to union loyalty. Moreover, process-based concerns explained additional variance in union loyalty beyond that accounted for by outcome-based concerns. Results are discussed in light of the justice and human resource literatures.
