Principal does not want to get into it iwth the teacher, problem feels it is easier to shush YOU and kick you child out htan to do the right thing. may even have told teacher to do this with your child. You can bet that your child is NOT the only one that this has been done to.
MAKE NOISE. Take it to the school superintendent, to the school board, to the county level, to the state level. Contact your state legislature and your federal legislature. This violates so very many LAWS, and is totally abusive.
I would ALSO contact the media, and keep contacting them. Show them the papers you have copies of.
It is time to take a stand for your difficult child.
I am so sorry the principal is as stupid and mean as the teacher.
any principal who showed me something like that would be sorry. The entire school would, because I WOULD have a lawyer and WOULD sue. (But my school district KNOWS this, has already entered an agreement for me NOT to sue them.)
Hugs,
Susie
