This paper reviews Bill Weddeburn’s seminal article on the concept of inderogability, published in 1992, in the light of the intervening evolution of European labour law. In the early 1990s the relationship between contract, collective bargaining and statute was becoming more fluid. Since the mid-2000s there has been an even more radical realignment. The familiar hierarchy of sources is dissolving into a polycentric arrangement of competing normative orders. As a result the operation of labour standards is increasingly influenced by fiscal law, free movement law, and the legal framework for European economic and monetary union. These developments present dangers to labour law but also opportunities for its renewal.
