> "The guy cleaning toilets does not need two more guys backing him up for the 2nd and 3rd shift. Dirty toilets wait until he rolls out of his bunk, or until the captain eats a volatile burrito, and someone wakes the toilets guy up to deal with that specific problem outside of regular duty hours."
That isn't how it works.
So there are all kinds of functional roles in the Navy (and I'm going off of submarines since that it was my experience was in), roles having to do with operating the sonar equipment, IT/comms equipment, torpedoes, and the engine room. So these people will be on watch (hourly logs, monitoring system conditions, etc.) and then after they are relieved they'll do whatever maintenance and cleaning they are assigned to. There is not a "clean-the-toilets" job role.
