Collective action of workers and economic freedoms: essay on an encounter in national and supranational legal orders.

Summary Collective action by workers - usually referred to in France as a strike - is subject to diverse legal treatment at both national and supranational levels. Following the Viking and Laval rulings of the Court of Justice of the European Union in 2007, national and supranational regimes of collective action are bound to evolve as a result of their encounter with economic freedoms, foremost among which are the freedom of establishment and the freedom to provide services. The study of these developments requires the combination of two perspectives. From a historical and descriptive perspective, the aim is to examine these regimes in order to understand their construction. To this end, the tool chosen is that of legal comparison, a comparison that is carried out at two levels: national (French law and English law) and supranational (ILO law and Council of Europe law). It is from a more dynamic perspective that the study then focuses on the interactions of these regimes with economic freedoms.
