This text aims to discuss transformations in the world of work and the working class, especially during the capitalist world crisis of the 1970s and 1980s. Understanding the punk movement as an important element that can give us clues of this process within the culture. Our hypothesis is that this movement was both a symptom and an agent. A symptom of a disintegrating working class to the work of an urban precarious. However, this movement also establishes itself as an active agent, especially in what concerns the debate around an agency in relation to the discipline of capitalist labor. We will focus on the movement of the city of São Paulo and the ABC of São Paulo, as well as its relationship with the working class of São Paulo. To do so, we will use primary sources, through elements of oral history, interviewing participants of the São Paulo punk movement and ABC. We will also visit the archives about punk movement of CEDIC (Center of Scientific Documentation of PUC SP), containing fanzines, discs, correspondences, etc. We will also use, as a tool, the analysis of punk songs and poems of the period, having as important conceptual element the conceptions of agency and experience present in the work of the English historian Edward Palmer Thompson. Still as a theoretical contribution, we will use some productions of books and articles about punk in Brazil and in the world.
