Throughout the Greater Saar-Lor-Lux Region, the development of border work has been accompanied by a diversification of its forms such as temporary cross-border labor. Temporary-work agencies have imposed themselves as new intermediaries of employment in these cross-border spaces, privileging the development of particular forms of employment and taking advantage of the different social and fiscal legislations operating in different jurisdictions, as they contribute to the recruitment of the cross-border labor-force. These detached temporary workers are relatively well-trained and well-qualified, and most of all they are tied to the temporary employment agencies. While such detachment of temporary workers remains the classical form of a flexible labor-force allowing for access to human resources not available in a given jurisdiction, it also represents a tool for the management of cross-border labor-cost differentials. On a larger scale, such practices of cross-border detachment threaten to speed up the process of deterritorializing systems of national law, and compel within the GR increased competition between national regulatory systems that have, notably, to do with finance and social protection.
