Obviously managers in a communist society won’t be bourgeoisie, right? But I imagine an organization in a communist society still needs people to coordinate everything, even if it’s run like a complete worker cooperative. So will they be elected by the workers? In that case, are they still workers?
They are workers. A person is a bougie in the simplest sense if they own the means of production which union leaders don’t.
Are the leaders of a worker-cooperative corporation considered union leaders?
