At our small primary school we have 3 regular midday assistants, two of whom started just over 12 months ago, just before I was appointed as HT (having previously been deputy). All middays were issued with a handbook, and received play-leader training, had an update on the assertive discipline policy, and were provided with stickers etc for positive rewards. We also have a reward system in the dining hall where the best behaved table is rewarded the following week by having linen tablecloth,after-dinner mints etc. I usually supervise in the dining hall at least 3 out of 5 days. Several days ago one of the ladies informed me about an incident involving a 5 year old boy who had been playing roughly on the yard and had hurt another child. She had sent him in to the teacher(who was on her lunch break, I was off-site that particular day), he had been spoken to, told he had lost his 'good to be green card' (and therefore 5 mins 'golden time') and sent back out. The midday took exception to the fact that he had been sent out again. What has upset me is that my chair of governors has been in to see me this afternoon as the midday has made a formal complaint about the incident. I am feeling really annoyed that she has gone over my head (that is how I see it) to the chair, I had already dealt with the incident, spoken to the teacher and child, and the parents of the child he had hurt, and we had made some changes as to how he should be dealt with during lunchtimes. Incidentally, it is rare that he misbehaves on the yard when teaching/ta's are on duty. Am I over-reacting? Has anyone else had similar situations or can offer advice? The chair did not mention the midday by name, but it was very obvious who he was referring to and he did not correct me when I discussed how I had dealt with the complaint the previous week.
