title: A model of union participation: the impact of perceived union support, union instrumentality, and union loyalty.
abstract: Perceived union support and union instrumentality have been shown to uniquely predict union loyalty. This study was the first to explicitly examine the relation between perceived union support and union instrumentality. Surveys were completed by 273 union members and 29 union stewards. A comparison of 2 models, 1 based on organizational support theory and 1 based on union participation theories, found that the model based on organizational support theory, in which union instrumentality was an antecedent to perceived union support and led to union loyalty and subsequently union participation, best fit the data. The model based on union participation theories, in which perceived union support was an antecedent of union instrumentality and led to union loyalty and subsequently union participation, was not supported. Union instrumentality was related to union commitment, but the relation was completely mediated by perceived union support.
