Rest and Recreation for Rejects?

While I do understand that the Imperium don't usually care about it's citizens health and mental well being.
Would it be too optimistic of me to assume that members of the warband get some downtime every now and again?

Does being on a Rogue Trader ship, in service to the Inquisition grant us some extra privileges not afforded to most?
Or is it round the clock either doing missions, maintaining gear for the next mission, and maybe even a hour or so sleep?

If we do get some breaks, what's it your Reject(s) do off the clock?
How do they unwind?
