we work 7- -12 hr shifts in 2 week period, and are scheduled a 24 hr o/c shift every other week, if called in we get time and a half for the hours worked and can only work up to 16 hours. if a nurse is still needed at the end of your 16 hours the charge nurse gets on the phone and begs for help. usually someone always comes in or covers. we have a small unit, only 20 nurses-5 birthing rooms and deliver 35-50 babies a month. we also take care of all gyn patients.
