There are not normally any unrated spacers on ships, apart from training ships. (A lot of training is done in VR simulations, allowing a great deal of simulated hands-on mentored work to be done early non-ship training.) Mindless labor on ships is done by drones; the small amount of such work for which drones are not suitable can be done on a secondary basis by the specialist crew.

To get assigned to a ship you have to complete some kind of specialist training. Spacer recruits who repeatedly fail to achieve this goal wash out of the Space Force, which has no great difficulty meeting its recruiting targets (which are low, since the SF is downsizing.)
