I work 3 days a week on a permanent basis covering classes when the class teacher has management time or PPA. I spend a morning or afternoon in year groups from 1-5.
In one particular class, I find the TA to be reasonably pleasant and efficient but inclined to overstep the mark. For example, last week when I was teaching he said to me, it's time to stop now when the children were doing a morning activity and it ran slightly over time. When I was working with a group for guided reading he told the children groups working on independent activities to pack up when I was clearly still working with a guided reading group. Occasionally when I have been out of the classroom with children and come back from PE/music etc he is sitting at the front at the teacher's desk and I have had to ask him to move elsewhere so I can teach.
He seems to get on well with the classroom teacher and I do not want to approach her about it.
It has been an ongoing issue and these incidents continue to reoccur. Has anyone got a diplomatic way of approaching this?
