The growth in multilateral working relationships (e.g. agency work, chains of sub-contracting and corporate groups) is causing Member States to increasingly scrutinise their traditional, contractual approach to the notion of ‘employer’. So far, little attention has been paid to the boundaries and limits that EU law sets when defining the employer. The lack of attention may have come to an end with the recent AFMB judgment, in which the Court ruled, for the first time, that the concept of employer in a provision of EU law had to be given an autonomous and uniform interpretation throughout the EU. Starting from the AFMB judgment, the author analyses the concept of employer in EU law. The author finds that the concept of employer in EU law can be described as ‘uniform in its functionality’: in EU law, the national concept of the employer is never absolute, but the circumstances and the way in which the national concept must be set aside depend on the context and the objective of the European legislation in question. Through this functional approach, EU law partly harmonises the various national approaches to the concept of the employer. Nevertheless, a lack of specific reasoning on the part of the Court may grant the Member States considerable leeway to uphold their own views on the concept.
