sounds a lot like the way my son was treated in year 4 because we were a day late for the start of term.....really hope you can sort things out. Some primary school teachers have a lot to answer for and have no interest in sorting out bullying because actually they have instigated it. Is there a chance to move him or HE?
hmmm it all sounds horribly familiar and predictable - some primary school class teachers are well out of order and as I said,do contribute to the bullying atmosphere IME. I do hope you can get this sorted but short of moving schools.....I just do not know. Is there just one class per year group?
I'd get hold of the bullying policy for the school and go through it with a fine tooth comb. Should the head still ignore this, I'd approach the council and take it from there. Most have an complaints procedure where you will be listened to impartially.
Wrt the desk and layout of the classroom- some classes in my own school and my DD's school have the teacher's desk facing a wall. The teacher would NEVER sit at the desk facing away from pupils during a lesson. They walk around, sit with a group of pupils, stand at the front etc. The desk is used before 9am, after 3.30pm and the rest of the time as a filing cabinet.
With the other things, I get the impression that the teacher believes it is a clash of personalities and not bullying. Hence separating the two children in the line, and moving both of them to new tables.
I agree that you should ask again for the anti-bullying policy. If they can't provide it within perhaps 3 working days, I would go to the LEA.
How old is your child? Poor little boy. If it would happen in my son, and the school would not be able to sort it out within 1 or 2 weeks, I would go to the school with my son and stay with him through the day. And if they ask me to leave, I would tell them that I think my son is not safe under the school care, so until they won't sort out the situation I will come and stay all day, every day. I am from England, so I know I could remove him from the school if I wish, but our children are entitled for a free (and hopefully safe) education, aren't they? If I do not do my job perfectly, I would lose my job. So if the teacher cannot deal with the situation since October, why the school does not remove her from the class?
