The chapter undertakes to analyze the notion of “migrant worker” as used in the EU
law. The scope of the term is discussed on the basis of the legislation and the caselaw
of the Court of Justice of the EU. As a result of the case-law, a gradual widening
of the scope of the term “migrant worker” may be observed. However, this wider understanding
of the term often faces challenges and obstacles from the national legislation
of the EU Member States, which not only elaborate more strict definitions of the term
but also provide restrictions for the application of the EU definition of the term. The future
development of the legal doctrine should focus on the barriers and obstacles that impede
the freedom of movement of workers. This is suggested also in the current European studies
on the subject.
