My parent's caretaker is an emotional bully and I can't take it anymore. What can I do?

Who's paying?

What hourly rate do you consider as overcharging? If the Caregiver is being paid through an Agency, it is not uncommon to be charged over $20/hour [depending on your areas going rate], to which the Caregiver gets a percentage of that amount.... from the amount her payroll taxes are paid by the Agency, she could also be getting health insurance, paid vacations, paid sick leave, possible time & half for overtime and double time for holidays.

If the Caregiver is an independent contractor, thus not working for an Agency, but on her own, the average is around $10-15/hour [depending on your areas going rate] from which she would take out to pay her own estimated quarterly income taxes, and take out to pay for her own health insurance. She wouldn't have paid vacation days, nor paid sick leave, and no time & half for overtime, etc.

The important thing, as mentioned above, do your parents like her? If yes, consider yourself lucky.... many parents refuse outside help, even refuse Hazel [old TV show from decades ago] if she came to the door. Then you would become the full-time caregiver.

Who pays the caregiver? If you pay the caregiver (from your parents account) then you have a right to speak up and question how much she's getting paid. Ask around at different agencies, find out how much they charge for what this caregiver does.

But if your parents like her keep your feelings to yourself and be grateful you have a caregiver that your parents like.
