In Italy the relationship between Law and collective bargaining - always conditioned by the difficult link of the industrial relation system with the political system - is evolving with a progressive reduction of the difference between heteronomous and autonomous regulation. In the last five years three phenomena have had a lot of influence: a) the transfer of national sovereignty, in an informal rather than a formal way; b) the verticalisation directed to the simplification of interests to be regulated; c) the fragmentation of the places of autonomous regulation. Nevertheless, the situation is still on moving. The "Jobs Act" - Law 183/14 and the application decrees - have increased the present trends, by using very old relationship techniques - introduced in Italy twenty years ago - which expose the new legislation to firm opportunism’s choices and some evident constitutionality exceptions.
