I'll try to be brief.
Recently moved ds2 (Y2) to another school because he was deeply unhappy in the class he was in. It was a class of 30 and there were numerous ongoing behaviour problems and he was coming out of school angry and frustrated and often tearful. I raised a few concerns over the last term with the teachers but they were pretty dismissive, although one of the TA's was lovely and really seemed to try to look out for him at playtimes. Eventually decided to move him to a new school and was as open and diplomatic as I could be in the circumstances.
My older son is still at the old school because he is very happy there and will leave in July anyway.
Ds2's old class was a job share and I know both teachers pretty well, since one of them has a son in ds1's class, and the other has a daughter who plays with ds3 at nursery. Since ds2 left, both teachers have barely acknowledged me, although I see one or the other every day when I'm picking up ds1. I texted Teacher 2 the other day to invite her daughter round to play with ds3 and got a curt refusal. Neither has even said hello to ds2 or asked him how he was getting on at his new school. Took Teacher 1's son out the other weekend with mine and she got her dh to drop him off and pick him up and hasn't said thank you when I have seen her since.
I'm not sure what I expected, but I'm struggling to see their attitude as anything but petty and rude. I was really careful not to criticise them as teachers to the head because I wanted to try to stay on good terms with them for everyone's sake but it looks like they have taken offence anyway. I have been very involved in said school over the years. Regularly help out on school trips, run stalls at school fairs, etc etc. It's not me, is it? They are being dickheads, aren't they?
