Labour inspectorates and other inspecting authorities with a mandate to monitor labour and employment standards (e.g. the financial police) have emerged as possible actors that can contribute to national efforts to combat trafficking. Today these authorities are expected to play a key role in tackling trafficking for labour exploitation (see, e.g., GRETA 2016) and in fact, in many countries, they have become involved in anti-trafficking efforts to implement international obligations. This policy brief summarises key findings of research conducted within the DemandAT project that examined the role of selected authorities mandated to monitor labour and employment standards in addressing trafficking in five EU Member States.
