The European Labour Authority (ELA) is an agency of the European Union established to ensure that EU rules on labour mobility and social security coordination are enforced in a fair and effective manner.

Its mission is to make it easier for individuals and businesses to benefit from the internal market by providing information and services, coordinating joint inspections, and facilitating cooperation between Member States.

ELA also plays a significant role in addressing undeclared work, posting of workers, and social security coordination across borders.
