Free movement of workers and rights that can be derived

In this contribution a non-exhaustive overview is provided of several aspects of free movement of workers in the EU. The author has been (and is) involved in several research projects on the posting of workers, the coordination of social security and workers rights in a cross-border context; this article is part of work in progress. It starts with an overview of the different relevant aspects of workers rights and provisions in three policy fields (social security, working conditions, labour and contract law). In the following sections these policy fields are briefly sketched out. In the last section some of the pending problems are listed.
