I want to know how I can get paid for taking care of someone. I stay with her night and day, have been for 2 years.

Who 'hired' you?

Is this a friend? Payment should have been discussed 2 years ago.
Difficult to get "back pay"
If the POA does not agree to pay you then you need to either accept that you are going to be without income OR you walk away. Tell the sister "I'm sorry I can not do this any longer without being paid. You will have to find someone else to care for --------"
No need to give notice just pack your stuff and go.

Hi Kathy, sound like my life.

You can get some , if your moms on Medicaid.

But if your sister is like my brother (POA) he refuses, and refuses to get mom on medicad

So I'm not sure how things are in your family, but I told my brother, he told mom, mom was mad at me treated me worse than her usual bad.

I was going to moms 3 days a week , I backed off to one day a week.

Had this and that out with my brother.

To make a long story short , brother now knows not to mess with me or I'm done, and mom is like so nice to me now. Not a fake nice.

I'm not getting paid, but in my case that wasn't what I wanted , I wanted respect. Now I'm getting it.

Anyways you may have to just plan stop doing to get your sister to listen to you.

If you need the money, please think of yourself, stop doing for mom and get a job. We should never put are life in jeopardy for are parents.

Best of luck

Why have you stayed with this person and are caring for her for 2 years, if you're not getting paid to do so?
Is it because you're living there rent free, and have a roof over your head?
How are you eating, and buying needed items for yourself if you have no money?
So if the sister who controls all the money, thinks that because you live there rent free that she's doing you a favor, she is sadly mistaken.
She must also pay you an hourly rate for your 24/7 care, at a fair market price.
And if she's not willing to do that, then you need to give your 2 weeks notice and you go out and get a real job that actually pays you, and move out.
I'm still confused why you have stayed so long with not getting paid.
I'm guessing that there's a lot more to your story than what you've shared.

Are you a roommate or did you agree to be a live-in in exchange for rent? Were you a roommate that inadvertently turned into a caregiver?

What state are you in?

Oh my! Do you have receipts of things you’ve purchased or spent? Maybe you need to start documenting every day and everything! Talk to the sister and ask to be paid or you are leaving…
