In Argentina, the central decades of the Twentieth Century were a period of deep changes in domestic work, both paid and unpaid, in which the demarcation of work and family was variable and conflictive, and in which domestic service acquired new meanings. The law-ranking decree 326, that regulates domestic service since 1956, is, in this sense, an important milestone. Although the protections that it warranted were more limited than the ones recognized for other workers, this decree constituted the first legal regime for domestic workers, changing the notions of justice related to domestic services even beyond what was established within the law. In this article, I reconstruct the legal and discursive strategies, both of domestic employers and employees, through the analysis of 369 dossiers initiated before the Consejo de Trabajo Doméstico between 1956 and 1962. I explore the appropriations of the law, and I show that both the appeal to gender stereotypes, and the changing demarcations of the limits between the intimate, the private and the public spheres, were central elements in the strategies described.
