I worked on a unit where we would sleep on our UNPAID lunch hour, in the break room.. where you could hear the code bell go off in an emergency. Then they changed it that we were not allowed to sleep on our UNPAID lunch hour, so the nurses would go to their car to sleep. At least when they were in the break room they were easily accessible. There were also times, rarely... if a coworker was not feeling well, others would cover her assignment so she could take a longer nap... this was not often, and only if the unit was not too busy. I feel what you do on tour time is your business... A quick nap can help you get home alive on a long commute!!! Corporate america is also looking into how power naps increases workers producivity!!
