Exchange ideology and member-union relationships: an evaluation of moderation effects

Based on studies of unionized nurses and water workers in the United Kingdom, perceived union support was associated with union commitment, union citizenship behaviors, and intent to quit union membership and switch unions. Instrumentality was less significant as an antecedent of most of these outcomes. In contrast to earlier findings on organization-employee exchange, although accounting for a relatively small percentage of variance, exchange ideology negatively moderated several of the relationships between support and instrumentality, on one hand, and commitment and union citizenship behaviors, on the other.
