CNA Abuse. There is a CNA at my Mother's Assisted Living who has been verbally abusive.

There is a CNA at my Mother's Assisted Living who has been verbally abusive to my Mother and me. She is very overbearing, hateful, loud, rough talking, has a temper, argumentative, lazy, has been caught sleeping on the job, etc. I reported her to the Supervisor's a couple of months ago. I told them at the time, I was afraid the CNA would seek revenge towards my Mom after they talked to her. They assured me their investigation would be private. Of course, it was obvious to me, by her actions, the CNA knew who reported her, and so it wasn't much of a secret. This CNA’s persona is very sweet when anyone of authority is around, like a Jekyll and Hyde. I had asked the supervisor’s if it would be possible for them to transfer her to another area. Nothing like this happened. They seem hesitant to do anything. At almost $4,000 a month, my Mother deserves better! I am there more often and longer than any of the other visitors, so have been able to observe more of what is going on. Of course, it is my word against hers since I have no proof, as she makes sure there are no witnesses to hear her abusive behavior. I do know she has been turned in for sleeping on the job from another person who observed her. So, this week, I was bringing my Mother back from an outing, and this CNA verbally attacked me out- of- the- blue about something very minor. I was in shock. With her angry persona, I am worried she might be doing something physically harmful to my Mother when no one is around. My Mother is very fragile, and has mild Dementia. I plan to talk to her Supervisor’s again, which will only make matters worse, but I have no other choice. As my Mother’s advocate, her safety and welfare is the most important. I have had no problems with any of the other CNAs. They are all great and very professional. Any advice, comments would be appreciated. Thanks in advance.
