This article unpacks some severe forms of exploitation of workers, resulting from the use of free provision of services for purposes that it was not intended to fulfil, under internal market law. It explores how this evolution of posting relates to the existence of a market resting only on the international assignment of workers, and proposes that the European Union (EU) takes steps to limit or prohibit assignment of labour, especially in the sectors (agriculture, meat sector, construction) where posting of workers, as some recent cases show, leads to extreme forms of exploitation that can be tagged as slavery.
