I am working with the same TA next year and to be honest, she does her own thing all week. She sits with the kids during the lesson time (just about) but any other time she’s doing self directed admin jobs. Whilst this is (usually) helpful and within her job role, it is taken to the extreme and she doesn’t do jobs for me or hear about the plans for the day etc. when I’ve approached directing her more closely before it’s gone down badly and she’s become angry and upset with me (sometimes for days!).
Do you have any suggestions of how to approach things with her in the new year?
