I'm a full-time live-in caregiver and I get my 40 hours each week, but from 6 pm till we wake up is supposed to be my "rent", even though I pay for all the groceries, cleaning supplies, cook and clean and the family doesn't acknowledge this unless I say something to them. I'm hoping someone can give me some advice on this whole situation...
I suggest that you go through an agency for your next placement. Your hourly rate may be less but everything will be above-board and reasonable.
I'm curious about the same thing moecam is -- are you caring for a family member? If so, the family ought to look into hiring people from an agency (they will need to hired more than one shift) and see if that person buys groceries and pays rent. Even if they continue to use you as the caregiver this would be an eye-opening experience for them.
If you are caring for a non-relative, give your notice. You can do better.
Or give notice and get a decent caregiving job.
