I hate to say this, but the break thing is part of being a CNA from my experience. I can probably count on both hands the number of shifts Ive worked the last year in which I have taken 2 full 15 minute breaks and a full half hour lunch. I will often work a 12 and a half hour shift with NO breaks, including a lunch break, simply because we are too swamped, and if I took a break the RNs I work with(Who also frequently dont get a break) would be in serious trouble.
When I worked in LTC, the situation was essentially the same. I worked an 8 hour shift and we didnt get a lunch break per se, as we ate our lunch while we fed a resident in the dining room. Sometimes I would take a morning break, again usually while assisting or keeping an eye on someone eating their breakfast in the dining room.
The break thing doesnt really bother me that much, but when it comes to injuring my back, I make no exceptions. If I feel its unsafe, I dont do it, period. I dont care if the person urging me to do something unsafe is an MD or an RN, if I think its going to injure me, I wont do it.
I wont even risk injury as an EMT. If someones arrival to the hospital is delayed because I cannot safely move them, and their chances for survival decrease as a result, so be it. That sounds harsh, but I learned early on that if you treat every call like your superman and are willing to sacrifice yourself for this ONE patient, your career in EMS would probably last a few months before you wind up seriously injured. Thats not to say I havent sacrificed my health and safety on a call, there are times when I have, but I try to keep those times to a minimum. But as a CNA....nope, wont do it. Theres no reason to.
