Oh, I’m with you about the nursing home bearing much blame, but not a “good chunk”. That animal beat that old man, no one made him. Again, see my earlier post...they often employ trash like this as that’s all they can get is uneducated, underachievers...not that being a CNA isn’t honorable, but this buck should be learning a trade, working his butt off, not tending old folk.
As to your experience in rest homes and doors open, often, a male orderly will be sent to assist a resident in going to the bathroom, then the door is closed for privacy...at least that was my guess.
