My son has autism so he is in a class of 8 students with a teacher and teacher's aide. His teacher has been gone since november of 2012. We received a call from the principal march 28, 2013 that she witnessed his teacher poking forcefully her finger in my son's head and saying foul mean things to him and the other students. SO the teacher is no longer at the school nor is she coming back. I was not informed of the matter in a promptly matter 5 months later is not acceptable. They are suppose to fill out a incident report and inform the parents but they did not. I did a background check on the teacher nothing bad on report but she does have 4 different ways she spells her name for different things. Can i sue for negligence?
