This work focuses on the temporary employment relationship, a tripartite relationship that brings together the user company (EU) that expresses a need for personnel, the temporary employment company (ETT) that provides a temporary worker and the temporary worker who will carry out an assignment in the user company, supervised by a manager. Because of its structurally transversal nature, the career path of temporary workers is often discontinuous and characterized by alternating periods of unemployment and work. Temporary work then becomes synonymous with insecurity and its management reduced to a simple replacement. By questioning the status quo and drawing inspiration from the theory of the segmentation of the labor market (Doeringer and Piore, 1971), which is taken up in the "flexible enterprise model" (Altkinson, 1984), this work aims to highlight the prospect of a career plan for the personnel made available, all of this by looking at the case of CAMRAIL.
