Research on union commitment is by no means a recent phenomenon as union commitment is a key factor in the determination of union growth. A thorough understanding of the subject matter is also highly relevant to the Singapore scene even though union membership has been increasing steadily over the years. Furthermore, a growth in the number of union members does not necessarily translate into active participation in the unions. This study examines the union commitment issue by developing a union commitment model that is based on the integration of three existing theories - the theory of reasoned action, the theory of planned behavior and the rationalistic approach to commitment. Regression results from a survey of 169 rank-and-file members reveal that union socialization and general union beliefs are positive predictors of both types of union attitudes (instrumental and value-based union attitudes). Moreover, pro-union behavioral intention to participate is found to be a strong predictor of actual union participation. Implications of the above findings to union leaders, managers and other practitioners are also presented.
