This dissertation aims to analyze the centrality of work in the demands of care and social reproduction within the framework of capitalist society, considering the dimensions of gender-race-class in care work. It seeks to delve deeper into the dilemmas of reproductive work in the context of capitalist society under the new morphologies of work, understand the approaches to reproductive work in Marxist feminist theories, and analyze the impacts of different forms of exploitation-oppression of women in the field of care work. The guiding question of this research is that care work, as it is mostly carried out by women, is not treated in much of the classical literature as work. Considering the historical determinants of gender-race-class exploitation-oppression, women are led to experience more deeply the conditions of subalternization and feminization of poverty, which is intensified with their greater presence in care work. The methodology used was bibliographical research on paid/unpaid care work in domestic spaces and data produced by the Continuous National Household Sample Survey (Continuous PNAD) of the Brazilian Institute of Geography and Statistics (IBGE) between 2017 and 2022, period in which the annual reports were made available. The data collected shows the insertion of women in care work with details of race, age, education, location, status at home, activities carried out, remuneration and working conditions (whether or not they have a formal contract). They explain the dynamics of care work in the period studied, allowing us to observe aspects of the sociosexual and racial division of work.
