This dissertation focuses on precarious informal employment used as a means of survival by non-femme black lesbian workers, whose effects unfold in the precariousness of their living conditions, manifested in the lack of access to income and work, to high-quality public health, to social assistance, and in a history of child labor, family abandonment, a situation of liberty deprivation, structural racism and the effects of heteropatriarchy in their lives. This study aims to analyze how non-femme black lesbians resist in the urban space of Rio de Janeiro by performing precarious activities in informal employment, as well as to understand their living and working conditions, verify factors of social lack of protection that precede the performance of non-femme black lesbian workers in the informal labor market and analyze how lesbophobia, racism, and misogyny, as forms of manifestation of the violence inherent in a capitalist, racist and heteropatriarchal society, are present in their daily lives. For this purpose, semi-structured interviews were conducted so that the workers could explain how they deal with informal employment and address issues about their living conditions considering the precarious elements of this type of work. The analysis of the data obtained has as theoretical references the studies on precariousness in the world of labor, black feminism, and lesbian materialist and francophone theorists. Thus, the relevance of this study is evident in the focus on the particularities of these workers, understanding their living conditions, from precarious informal employment, in which vulnerabilities and social unprotections that affect these women who do not express hegemonic femininity were verified, which also includes the desire to build a future with decent and safe employment.
