NON-DISCRIMINATION OF WORKERS.
Freedom of movement and residence for persons in the EU is the key of Union citizenship, established by the Treaty of Maastricht in 1992.
The concept of the free movement of persons has changed gradually in time:
1. 1957: The first provisions on the subject, in the 1957 Treaty establishing the European Economic Community, covered the free movement of workers and freedom of establishment, and thus individuals as employees or service providers.
2. The Treaty of Maastricht introduced the notion of EU citizenship to be enjoyed automatically by every national of a Member State. It is this EU citizenship that underpins the right of persons to move and reside freely within the territory of the Member States.
3. The Lisbon Treaty (2007) confirmed this right, which is also included in the general provisions on the Area of Freedom, Security and Justice.
