Some must be free, some serfs, some rulers, some subjects. Revolution demands, in the interests of socialism, that the masses unquestioningly obey the single will of the leaders of the labor process. It does mean, however, that the half dozen or so tasks that I regularly do must be roughly as empowering as the different half dozen or so tasks that you regularly do if we are to participate as equals in council decision making. In most workplaces there are hundreds of basic tasks. One organizational option is to combine tasks with the same qualitative characteristics into homogenous jobs.
Some workers take phone messages and keep records.
Others do research and manage. Ever one does one level of task and many more people have rote than have creative assignments. This is the capitalist and the coordinator approach. A better option is to combine tasks into job complexes each of which has a mix of responsibilities guaranteeing workers roughly comparable circumstances. Everyone does a unique bundle of things that add up to an equitable assignment.
