Mom lives alone in big house in NC. Fall risk. Only let me involve a care agency last year. They do shopping, errands, and transport of my mentally ill sister from her group home to mom's. Recent resumption of services after forced bed bug intervention. Sis is coming back home. There is one of the transport workers, who brought mom some food for Thanksgiving, when agency service was suspended (I had someone there pitch hitting during this time). Nice, huh? My mom wanted to xmas shop, but no one from the agency was available. So, this same worker came by (not on agency time or schedule) and helped mom out. Mom said she paid her a little to do this. I am on mom's account, checked it, and see she gave her $150. She has brought mom little crafty gifts shes made as well. I know mom loaned her money previously, which appeared to be paid back. I am an LISW, and know what a conflict this is. I think I found the workers phone #. My instinct is to call her, and tell her not to continue to do this. I don't want to get her fired. But, my mother's prior caretaker (of mom's choosing) had a similar profile, and ended up stealing $ -it took years to convince my mom of this. Advice?
