The authors replicate and extend the research on future workers' union attitudes, organizational beliefs, and work ethic. Selected demographic and attitudinal data were collected from a sample of 644 students at a small, western Pennsylvania university. Compared to earlier research on pre-employment predictors of union attitudes, this study is based on a much larger sample size and includes a cross-section of majors. The results offer additional support for the family socialization process; in general, future professionals and business managers are more sympathetic to labor unions if they were children of union members. In addition, the results show that student major has a significant and systematic impact on both positive and negative union attitudes.
