I work in a high volume cardiac cath. lab. and full time you are on a rotating call team one 48 hr./month - and one 12 hr. week night. Part-time = 48 hr.weekend/month. We are paid $8.to $9./hour to carry the beeper and be available. In my state you must be paid at least minimum wage for being on call. If we are called in we get OT and all the differentials that apply. We always get called in on the weekends, usually more than once - one time it was 32 out of 48 hours. We barely got home before we were turning around and going back in. As tiring as it is there are saving graces - the patient is critical so it keeps you and your team alert and on top of your game, requesting the Monday off after your weekend call = sanity, those power naps between calls are wonderful! Finally that paycheck sure does put a smile on your face!
