How does the European Union allow workers to move between member countries?

The European Union facilitates the movement of workers between member countries through the principle of the free movement of people, which is one of the "four freedoms" that define the European economy.1

This framework ensures that citizens of member states have the right to live and work in other EU countries, fostering economic integration and mobility across the union. By removing barriers to employment, the EU allows individuals to seek opportunities across borders, which has contributed to significant population mobility within the continent since the union's establishment.12
