The essay examines the possibility to ri-found a new scientific paradigm for labour law, in the face of the crisis of the traditional one and his final overcoming. It examines three traditional functions of the old paradigm: the regulation of competition, the emancipation of the employee, the conditioning of the authority of the company. All these components of the historical model are facing a profound transformation. Labour law, in order to maintain its regulatory functions, must recover the capacity-build, political and anthropological before legal, to balance the interests at stake, according to the teaching of Giorgio Ghezzi.
