Who decides what kind of work a citizen may or may not do in socialism?

In a socialist system, the government or state typically plays a central role in determining the types of work citizens may engage in. This is often based on collective needs, planning, and the overall goals of the economy, with an emphasis on equitable distribution of resources and services. Decisions may also involve input from workers' councils or cooperatives, reflecting the interests of the community. Ultimately, the aim is to align individual work with societal goals rather than purely market-driven choices.
