These guys have to work 40 hours per pay period, which is two 24 hours shifts every two weeks. This is just slightly more than 4 days a month. They will sometimes work four days in a row, the last two days of a period and then the first two of the next and can go 20+days between shifts.

160 hours isn’t much when you are getting paid to sleep, eat and hangout. It’s just 6 days.
