I started in a new school on a maternity contract in January. I have one top set who I think I feel I teach well and have had a good relationship with. However, I have found out that they have been going to their HOY with complaints/allegations against me saying that they have a bad relationship with me and that I don't praise them enough. Also, that there is misbehaviour in the lessons although they have only managed to name one pupil who has behaved badly. It appears that the HOY has taken all of this tittle tattle seriously and has passed it on to the deputy head who walked into my lesson last week and sat there. He then reported back to my HOD that it was a good lesson and that he hadn't seen any sign of the alleged bad relationships between me and the pupils. It was only after all this had happened that I inadvertantly found out about the complaints and the "investigation". Today someone in the class did behave badly and I logged this on the system. I immediately got an email from the deputy head saying that this had been brought to her notice (presumably again by the HOY). She asked to meet with me and my line manager to discuss. The time and place I have been given to discuss this is before lessons, in the school forecourt/driveway of the school where she will be on duty. I am amazed to find myself in such a Kafkaesque situaiton where incoherant allegations have been made and investigated behind my back. I have come to this school from a truly outstanding school and I have also taught in the top independent in the country. I have never been treated with such a lack of professional courtesy before and am not sure how to respond. Is this normal behaviour in schools? Any advice on how to proceed ? Thanks in advance for your help.
