Why Join? Why Stay? Instrumentality, Beliefs, Satisfaction and Individual Decisions on Union Membership
To understand individuals' union membership choices it is necessary to examine decisions both to join and to leave (exit) unions, observed when employees are in jobs where unions are available and there is freedom of choice on union membership (‘open’ jobs). Using multivariate analysis of survey data, it was found that sympathy towards unions was the most powerful influence upon union joining, but had little impact on union exit, which was more a function of the perceived instrumentality of membership. Employee perceptions on union in-fighting and cooperation with management influenced union membership, as did the outcome of involvement in industrial disputes. Satisfaction with union delegates was a key influence on attitudes and membership. Employee trust of management only influenced exit behaviour through its interaction with satisfaction with union delegates. Job satisfaction had a complex relationship with union membership that is disguised in aggregated studies.
