Where did you get the information you have about the teacher's language? From your child? If you're child is not a native English speaker and neither are you, isn't it possible that there's a misunderstanding? For example, I have never heard "shits on you" anywhere in the US. I wonder if the teacher said something like, "If you don't finish, it's on you." So the "sh" from "finish" get attached to the "it's" and your child misunderstood. Or maybe some other kids thought it sounded like "shits" and they started giggling or talking about it during lunch. "It's on you" is a common expression meaning, "It's your responsibility."
Who told you about the foot on the chair? Did you witness this yourself? If not, it's from your child, right? And what is the problem with a foot on the chair? Does that mean something really negative in your country? Even if it happened, is it possible the teacher was climbing on a chair to reach something high up? Perhaps she has a sprained ankle and was taking the weight off the injured leg. It could be anything.
Why do you think she is withholding books? Is it possible that your child is working on something different because of his ESL program?
Is it possible that your child is in a parallel program, that he's in the regular class for some things but is using other materials and taking different tests because he's not a native English speaker?
Did you go to the school's parent/teacher conference? Did you discuss this with the teacher? Find out if there is a translator who speaks your language as well as English who can also attend meetings so that there is no misunderstanding due to a language barrier. Also meet with the coordinator who handles all the kids in the school like your child, who are learning English as a Second Language. Find out what the plans are, the books, the extra help, the tutoring.
Find out about the school's bullying policy. You cannot assume that the teacher hears every single remark that every child makes to another child. Maybe she didn't hear it. Maybe she spoke to the bully directly without your child hearing it.
I think most of this is a misunderstanding or just plain incorrect info. I also think it's possible that your child, like so many others, has told you that "the teacher doesn't like me" or "I'm trying my best and she doesn't see it." Some kids who are not trying their best are happy to make excuses to their parents.
And I disagree with the person below who said you need to get into that classroom every day. That is not allowed in most schools! It's inappropriate to have parents in classes hearing everything that other kids are saying or hearing what the teachers and aides say to various students with medical issues, learning issues or language issues. You absolute do have the right to request that the school psychologist, principal, assistant principal or guidance counselor spend some time in the room observing, however.
It seems to me that you have worried about this for 6 months and you didn't understand what your parental rights and responsibilities are. You have the right to go to the school and express your concerns, but also say that you aren't sure what has really gone on in the class and you would like it explained to you since you are not familiar with American schools. If you go in with a cooperative attitude, you will learn much more.
