In this exploratory-descriptive research, the author looks into the identification of the factors concerning the present work model in Rio Grande do Sul State prisions, Brazil. This criticized model is responsible for the difficulties in promoting a reasonable resocialization of the prisoners. Simultaneously the author suggests important changes in the conquest of a more expressive achievement toward the expected resocialization. Data were collected in examining penal hanbook and references and chiefly by means of semi-structured interviews with twenty prisioners. Collected data were analyzed according to content methodology; results are presented in five final categories: (1) prisonal work; (2) prison system identity; (3) ideological resocialization; (4) prisional work influence on personal growth; (5) prisional work conditions. It was noticed that Penitentiary Administration ignores the importance of a etbter relation among psychological motivation, suffering and a legitimate pleasure in accomplishing prisonal imposed work, in overcoming huge problems and challenges and in reaching the intended prisioners' resocialization.
