The extensive fieldwork and desk research carried out by FRA is the first to look comprehensively into various criminal forms of severe labour exploitation of workers who move from one EU Member State to another or from a third country. It aims to fill the knowledge gap, thus challenging the current climate of implicit acceptance of severe labour exploitation. This research aims to support EU institutions and Member States in preventing severe labour exploitation, monitoring situations where severe labour exploitation occurs and making victims’ right to have access to justice a reality.
