Close cooperation between EWL members has resulted in guest lectures and joint research, fostering the study of comparative law. The group always addresses issues from an interdisciplinary perspective, defining labour law and social security law from a social rather than a legal viewpoint. When analysing social and legal problems its researchers involve all branches of law pertaining to the issue and use relevant meta-legal research results from sociology, economics, history and philosophy. The research activities of the group have resulted in several publications and contributions to books and journals.

The EWL also holds international colloquiums or seminars. In the past, colloquia have been held on issues such as European Works Councils (Antwerp, 1998), Restructuring (Strasbourg, 2001), Fundamental Workers' Rights (Antwerp, 2002) and Equal Treatment (Cassino, 2003). In 2004 an international seminar took place in cooperation with the ILO on 'The application of ILO standards in national law'. In 2010 a conference has been held on Health and Safety at work (Rome). The group participated in a colloquium in Strasbourg in 2010 on the application of directive 96/71/CE (posting of workers).

Cooperation between the units has resulted in various international publications. "European works councils: a legal analysis of the European Works Council: towards a revision of Directive (EC) No 94/45?" was published in 1999. In 2004 a book has been published on restructuring and the situation of workers (Strasbourg). The tenth anniversary of the group has been celebrated by the publication of a book on fundamental social rights in Europe (2009). In 2010 members of the group have contributed to a study on collective actions and fundamental freedoms in Europe. The proceedings of the Cassino/Rome colloquium on health and safety at the workplace will be published in 2013.

Intense and constructive cooperation between members of the EWL has led to (joint) studies of comparative law in national periodicals. Furthermore, it also fosters the practice of comparative law in doctoral and post-doctoral research. Doctoral researchers have conducted research abroad, providing an added value to national legal research, a precondition for establishing a genuine European ius commune. A comparative study of the transposition of European directives is a qualitative innovation in terms of European labour law research.

The EWL or their members participate in projects of the European Commission of the European Union.

The EWL aims to study them from a European and international viewpoint, and in an interdisciplinary legal framework. Social security law and labour law cannot be studied effectively without examining the complex interplay between scientifically related disciplines such as labour sociology, social history, economics, and philosophy.
