This paper aims to provide a simple trade union model which highlights some of the distinctive institutional features of French unionism. The model focuses on the determinants of militancy and membership in a frictionless economy. It is shown that a non-Walrasian labour market equilibrium exists wherein real wages, employment, union size and militancy are jointly determined. In comparative statics, the model predicts a negative relationship between militancy and membership.
