This paper generalises the standard Neo-classical analysis of equilibrium in the labour market. Determinants of labour productivity are analysed in terms of an output density function leading to the definition of generalised production functions. In this framework, a firm's optimal choice implies a two dimensional law of labour demand for both workers and hours. Equilibrium in the labour market presents a disconcerting property : in a pure competitive world, where unemployment is nil, overwork might be a natural state.
