Globalisation and internationalisation have had significant consequences for the regulation of labour markets in recent decades. This volume addresses some of the questions raised by the necessary rethinking of labour law-related issues. Labour and employment law have become increasingly interdependent at all levels, while simultaneously an increasing fragmentation of legal sources has occurred. This collection of essays provides different perspectives on aspects of these processes, in international or European perspectives, in the light of fundamental human rights or with a view to Swedish labour and employment law. The volume ends by looking into the future through the lens of the fragmentation of labour and employment law.
