My daughter is in the 5th grade at a small catholic school in Louisiana. Her teachers daughter and I used to be best friends. She is a terrible alcoholic. My husband, who is now deceased, helped her get out of 3 DWI offences. On the 4th one, I told her we could not help her anymore. Since then my child has been bullied by her teacher, harassed. For example, she puts my child's desk in the corner with her back to the class. The punishment my daughter receives is different from all of the other students. She has to sweep the classroom and write lines, not just write lines. She accuses her of talking in class and makes her put her name on the board, even after the student talking admits it was not my child, it was her. She has on several occasions told my daughter "I hope you fail this test." She has also told the principal in front of me that she has a difficult time keeping her personal feelings for me out of the classroom. The principal told her this was unacceptable as a teacher. She also told her she could not isolate my daughter, or any student , from the class. There was even a meeting held with the Principal, Administator, and several other parents one week ago. Since then, my daughter has been in the corner with her back to the class. I am going to have a meeting with the administrator today at 5pm. Any advice? Do I have a viable lawsuit?

Lawsuit? I doubt it.
But definitely speak to the head of the school, and get your child moved to a different class. If it is not resolved, pull her from the school and move her to another school.
My daughter was bullied by her kindergarten teacher. And it is NOT OK.

My son was bullied by his first grade teacher. He went to a small private school that I worked at. We were a close knit group, but I had always sensed that this teacher didn't like me. I kept giving the teacher the benefit of the doubt. In the end it was disastrous. By keeping your daughter in that classroom you are, in effect, allowing her to be prey for someone who sees you as an enemy. She is being abused and humiliated. Your job is to protect her. Get her out of that environment NOW and then worry about addressing this teacher's poor behavior.

Also, go back and read your post. You know this woman is an alcoholic who has an impulse control issue. She cares very little for herself or her loved ones. If she did she wouldn't drive drunk multiple times. She is also someone who holds a grudge and has a (self admitted) hard time keeping her personal feelings in check. She has openly declared war on your baby. I know this answer is harsh but I'm sitting here getting sick to my stomach at what's happening to your daughter and I'm wondering where the disconnect is. You're upset but are wondering about a lawsuit to punish the teacher - when really it should be the opposite. You should be wondering how quick you're able get your child out of that classroom and away from a monster. If you leave your daughter in this class for one more day you will be just as guilty as that nasty, black hearted teacher. Your job is protect your daughter. Protecting her doesn't mean talking to the principal or lodging complaints, it means STOPPING the abuse. Who cares about lawsuits?
