I work in a home that is understaffed and each person works ten hour shifts alone juggling the care of a dozen residents. There is one male resident who is full assist with everything & he seems to be angry about being assisted by an opposite-gender caregiver. And whenever I have to help him to bed or get him up he hits me which leaves bruises on him. I'm as nice to him as I possibly can be, even when I'm hurt and angry. His family is very suspicious of everyone and I'm afraid they'll try to get me fired. I document everything but have no witnesses since I'm alone. I don't know what to do.
