A model of a critical union commitment dimension - willingness to work for the union - is proposed and tested. Given the decline in union density in most advanced industrial societies, unions all over face the need for increased member activism. Organization and social psychological theories, along with previous empirical research, are used to develop the conceptual model, measures, and predictions. These predictions are tested via a 2-stage regression model, using data from a large sample of Swedish professional union members. As predicted, both attitudinal commitment and subjective norms are critical influences on the individual's willingness to work on behalf of the union. These results suggest that future research on union participation should focus on the determinants of behavioral intentions given the high correlation between willingness to work for the union and actual participation.
