Using nationally representative workplace surveys we examine the relationship between unionization and workplace financial performance in Britain and France. We find that union bargaining is detrimental to workplace performance in both countries. However, in Britain the effect is confined to the declining proportion of unionized workplaces where there is active collective bargaining. In the French case, the effect is confined to the minority of cases where unions have high density and where unions have a reputation for militancy.

Using nationally representative workplace surveys we examine the relationship between unionization and workplace financial performance in Britain and France. We find that union bargaining is detrimental to workplace performance in Britain and that this effect is larger when unionization is endogenized. In France, union bargaining is associated with poorer workplace performance but the effect disappears once unionization is treated as endogenous. However, high levels of union density do have a negative impact on workplace performance in France.
