Im not 100% sure what you are asking here. People will voluntarily contribute to the production process in whatever capacity they chose according to their ability. Most likely people will chose to engage in a wide variety of different kinds of work and why not ? Variety is the spice of life
What they as individuals draw from the community pot is not affected by what work they may have done. As I said there is no quid pro quo set up. The link between production and consumption at the level of individuals is thus severed in a socialist society.
It is a different matter entirely when we are looking at society as a whole. At the social level, production and consumption will obviously continue to be closely linked. Society as a whole cannot consume more than what society as a whole has produced. Productive effort will be guided consumer demand as expressed particularly via a self regulating system of stock control - a key insititution of socialism in my iopinion. Individuals will be able to see for themselves where work is needed and volunteer themsleves accordingly as they see fit with prpduction units no doubt making known to the public their labour requirements on a contunually updated basis
In other words, the individual's capacity to chose whatever work he or she wants to do will be within a social framework in which production will be constrained by the overall pattern of demand . People are both consumers and producers and will have an interest in seeing that what is produced in general is tailored to consumer demand in general.
