The research is driven by the following problem: how do imaginaries of the use of law influence Brazilian policies to regulate platformized work and how can the expansion of these imaginaries contribute to the transformation of these policies? To this end, we analyzed the text of Proposed Law 12/2024 (PLP 12/24), which presents a proposal to regulate the work of ride hailing app drivers, the debates that led to its drafting and institutional digital solidarity economy policies in the country. The study is deductive, based on literature on socio-technical imaginaries, platform critical studies, critical law theory, as well as institutional norms and Brazilian experiences of platform cooperativism. Techniques and technologies do not exist in a vacuum, but are shaped by historical, social and ideological contexts, which align their existence and use with socio-technical imaginaries. Law, as a technique for regulating social relations, also emulates certain imaginaries, especially as its form reproduces capitalist patterns of sociability. PLP 12/24 was drawn up after tripartite debates involving representatives of workers, platforms and the government. Its text aims to promote better working conditions for app drivers by recognizing legal guarantees, without, however, substantially altering labor relations. The pattern of work based on the opposition between workers and owners of the means of production is maintained. This way of using the law is linked to a closed social imaginary, which prevents thinking about new patterns of production and forms of work organization that could increase workers' autonomy and sovereignty in relation to the organization of their work activities. On the other hand, public policies within the digital solidarity economy have been promoted at different institutional levels, encouraging new ways of organizing platformized work activities. At the national level, there are federal government programs to promote the solidarity economy; at the regional level, there are initiatives such as partnerships between the government of Rio Grande do Sul state and the federation of ride hailing app cooperatives Liga Coop, which is active throughout Brazil; and at the local level, there are programs such as the cooperative incubation project funded by the city of Araraquara. The preliminary conclusion is that it's necessary to think of alternative ways of instrumentalizing law that can expand regulatory horizons beyond the recognition of legal guarantees, creating opportunities for the development of new work patterns on digital platforms through public policies.
