This paper presents an alternative implementation of firm-level collective wage bargaining, where bargaining proceeds as a finite sequence of sessions between a firm and a union of variable size. We investigate the impact of such a `gradual' union on the wage-employment contract in an economy...

Short-term contracts and exogenous productivity growth are introduced in asimple wage bargaining model. The equilibrium utilities corresponding tomilitant union behaviour are independent of the contract length. The wagedynamics are linear if strike is credible (low wage shares) and...
