I currently work as an AST in the London Area. Having started my secondment to a struggling school in North London; I had been there for one day a week for four weeks; I was apprehended at the end of my Year 11 parents evening by my Principal. He asked me if I could go into my secondment school the following morning and teach their Science NQTs timetable as the school was being Ofsteded and the SLT had asked her to stay at home. Firstly; I must state I am a Chemist not a Physicist and this lady taught primarily Physics; secondly it was 8.30 at night; thirdly the school expected me to plan all the lessons outright. I foolishly agreed to go in to support but was not happy about the situation and had been assured nobody would visit my classroom. On arrival I was met by the school's lead deputy who handed me a wedge of data and escorted me to the conference room and introduced me to Ofsted team as the Acting Head of Science... I am not sorry to say I revealed everything to the Inspectors and was promptly sent home and threatened with dismissal from the Secondment school's SLT. I never did return. The school went into special measures and I left my school after a big disagreement with the Head over acceptable and reasonable behaviour... What is the most unprofessional situation you have been placed in?
