This morning one of my parents (who is a parent governor) came into the classroom and said "I'm just confirming it's ok for me to come and observe you this afternoon?" my response was that I knew nothing about it and that it is my PPA time on a Friday afternoon. He said that he would come in anyway as he had promised his son he would be in to watch his lesson. So he is currently observing my poor TA covering my class. My headteacher is not here today but I have been informed by the secretary that she has known for weeks. I am thoroughly annoyed to say the least, I feel that I should not only have been told that he was coming to observe me but also asked. I actually do not think that it is appropriate for a parent governor to observe their own child's class teacher as it raises issues of their motives? Do you think that I am right to be annoyed and how do you think I should broach the subject with my (unapproachable) headteacher?
