The present article is the result of a study on the strategies undertaken by the factory`s ground-floor workers to achieve chief positions. Six cases of workers were investigated through the reconstruction of their occupational trajectories and estrategies. As a conclusion, the strategies are not the result of a rationality but of an effort made by the factory`s ground-floor worker to get a job and to maintain it due to the precarious formal professionalization and the small social and cultural wealth related to his class origin.
