I'm thinking of leaving, I've already told the head I am applying for new jobs but will possibly be resigning. When he asked why I told him that I didn't believe the current role offered me any opportunity to progress with my skills or in my career, I also told him that I don't think classes have been allocated fairly which affects my performance - and my pay as a consequence. He has offered to have a meeting with the head of department to discuss our roles and called the HOD for a meeting last week, there is now some hostility between us and the HOD thinks I am now after their job. I'll explain more: In my first year of teaching there I was only given key stage 3 classes, no top sets or bottom sets, just the large and sometimes difficult classes in the middle. The reason for not giving me any key stage 4 or 5 was stated as "helping me to settle in". Three years later nothing has changed, the HOD still has all key stage 4 and 5 - small groups with less that 15 students in each class - along with the top and bottom sets from key stage 3. In terms of student numbers, I have over 500 students and the HOD has 180. In addition, the HOD also has a lot of frees on his timetable in addition to management and ppa, I don't have any. This week the HOD had a meeting with the head to discuss this and has hardly spoken to me, but has made comments about me being "after his job", I think he has also discussed this with students as some who hang around the department in breaks are also falling completely silent when I walk in a room and he is with them, its all very awkward. One student in key stage 3 said to me this week: "Is it true that if you pick GCSE you only have Mr ...... and not you?" reply: "At the moment that's correct but it may change", to which the student said: "Oh, I've heard he's a much better teacher than you". I was almost in tears at this point. To add to this, our performance is frequently compared and referred to in meetings, "Mr .......'s results are much better than yours, all his students are on or above target and there are few behavioural problems, what are you doing wrong?" I have tried explaining that I think this is because he as the very small low ability groups with less than 10 in the class, the top set, and the KS4/5 who have OPTED to take the subject, but SLT won't listen to me. I would like the chance to prove that I CAN get good results but I feel this is holding me back. I also think that the way our classes have been allocated, and our timetables are totally unfair. Unfortunately I have no control over this, in our school the HOD has control over how this is allocated.
