The text provides an analysis of the investigations carried out on teachers' work in the 1990s in Brazil, identifying the main conceptions on the theme and the researchers' analytical approach. First, the study results are briefly presented, and then an analysis of the production on teachers' work is developed in the light of the Marxist framework. For such, a study of the meaning of labor in capitalism and the distinctions between work processes and capital production processes is carried out, as well as a study of the conception of work producing capital. This basis has allowed a discussion on the relation between teachers as workers and the social classes, which, in its turn, leads to the discussion of the role of teachers, not only as teachers, but also as a class, in the process of revolutionary transformation of capitalism.
