"The authors proposed a model of antiunion attitudes and prounion attitudes as predictors of American college students' willingness to join a union (N = 1,245). Structural equation modeling results indicated that antiunion and prounion attitudes are moderately related and both show similar strength in predicting willingness to join. In addition, a general antiunion factor is shown to underlie specific antiunion attitudes, whereas items related to prounion attitudes are shown to reflect a general prounion factor. The utility of the model was supported based on initial and cross-validation samples (ns = 623 and 622, respectively). Implications for measuring union attitudes and recruiting union members among college-educated workers are discussed."
