When your space slaves aren't mining, connecting themselves to tubes and hoses for feeding or breathing, or polishing their perma-spacesuits they need to be locked away. Space-slave miners on the Great Daughter have the displeasure of being bound up in rubber bags and hung upside-down before being stuffed into cramped rubber-lined lockers one after the other. The tight bag, the cramped confinement, the stale and thin air, the unending squeaking and muffled HMMPHs of the other slaves, the life support hoses, all of it gets inside of their heads to remind them where they belong and what they are. They're taken out at random whenever they're needed so any time demand for those minerals falls the lockers stay full. Hours, days, months can go by being stuck inside those rubber bags as they live through a series of bags and tubes knocking their squeaky boots together as they whine and struggle inside the lockers. For those few lucky slaves on the skeleton crew during paused production periods, the nights are restless as all the rest of the slaves struggling inside their confinement keep them up. The muffled constant MMPHHs, NNNGHs, and NNMMPHHs and constant squeaking could drive anyone nuts. Hopefully though they get selected in the morning to come out~
