Abstract: In March 2016 the European Commission proposed a revision of the Posting of Workers Directive (Directive 96/71/EC of the European Parliament and of the Council of 16 December 1996 concerning the posting of workers in the framework of the provision of services). Two years later, the co-legislators have adopted the revised Directive (Directive 2018/957/EU of the European Parliament and of the Council of 28 June 2018 amending Directive 96/71/EC concerning the posting of workers in the framework of the provision of services). This Article seeks to explain how this reform builds on the principles developed in the case law of the Court of Justice and eventually managed to upgrade the Posting of Workers Directive into an extended package of protective labour rules that nevertheless remains within the boundaries of internal market legislation.
Keywords: free movement of services – protection of workers – posted workers – Posting of Workers Directive – Enforcement Directive – equal pay for equal work.
