Since 2001, 'quality of employment' has been at the core of the political, academic and practical agenda, and has fed a wide-ranging debate. For the first time, a scientific work takes stock of the legal and normative understanding of quality of employment in Europe. In order to develop an interdisciplinary dialogue, the book underlines the importance of law in the debate on quality of employment and suggests how European concepts and tools might be adapted to enrich scientific reflection by employing a rigorous legal approach. To this end, the authors analyse the relevance of the concept of quality of employment in international, European and comparative law, examining a range of topics such as collective and labour rights, social security, non-discrimination and equality at work. Lastly, the authors examine the topic from the 'Capabilities' perspective, proposing concrete and realistic paths for maintaining the European concept of quality of employment and European social Law in the framework of the ILO Decent Work Agenda.
