How do union membership, union density and institutionalization affect perceptions of conflict between management and workers?

This article contributes to debates about trade unions and conflict by studying how individuals’ perceptions of conflicts between management and workers relate to trade union membership, country-level trade union density and institutionalization (collective bargaining coverage, centralization and policy concertation). Hierarchical multi-level models are fitted to data from the International Social Survey Programme from 2009. The results show that union members tend to be more likely than non-members to perceive management–worker conflicts and that this appears not to vary substantially between countries. However, regardless of union membership, individuals in countries with higher trade union density and with policy concertation tend to be significantly less likely to perceive conflicts. These findings highlight the risk of atomic fallacies in research limited to the individual-level effects of union membership. Contrary to an argument often raised by pluralists, neither bargaining coverage nor centralization has significant effects. Overall, the results question depictions of trade unions as divisive organizations.
