An intra-community seconded worker is an employee temporarily sent to France by an employer established in another EU or EEA member state, or in Switzerland. 

They carry out a time-limited assignment while maintaining their employment contract with their original employer and the hierarchical relationship for the entire duration of the assignment. 

Under certain conditions, they can remain affiliated with the social security system of their usual country of employment, in accordance with European social security coordination regulations. Social security contributions are then paid in that country by the employer.
