Background: Classroom teacher for about 10 years, effective enough with most of my classes (but had two classes I really struggled with) and liked by most students, became disillusioned with teaching and went onto supply, found I was actually valued by staff and many students alike in short- and medium-term roles, so decided to brave teaching again.
Took it slowly and went for a medium term cover first and the behaviour of my classes there utterly destroyed me; I left the job early after the minimum period stated and got a shitty reference as a result (even though the school practically begged me to stay on longer), but found another teaching job the day after I left.
Was kept on a string of temp contracts due to shitty reference and left again after a few years - with a successful track record with regards to results and good relationships with many students, although again I had two tricky classes I shared, who got on well with their other teacher, but who I could not crack.
Went on to middle management in a difficult school, had behaviour issues in most classes (as did almost everyone, due to the nature of the school), but again my results were average and my reference from that place was apparently stellar.
Left again after a short period into a new middle management post. I have been there a few weeks now and I am once again struggling with behaviour. The kids are difficult due to a string of supply; I teach a difficult subject and while most of KS3 are fine, I struggle majorly with behaviour in all bar the top sets of KS4.
I feel like I just can't teach anymore. I've gone from being a good teacher with above-average results to struggling with behaviour; I feel utterly overwhelmed by workload and have done for years and little things like a few weekends of sick children at home on the trot and I'm back to hating the job.
My manager is happy with me; but they only observed me with a KS3 class, but my issues with my KS4 classes are becoming quite well-known. They say kick them out and keep asking for help, but I don't trust that it won't come back to bite me and I can hardly kick 10 of them out every lesson.
I've changed schools a lot over the last few years; so I've rarely had time to become established again. I guess my question is, have I really lost it and cannot teach anymore (like many of the students will tell me now) or do I just stick it out for two years, knowing I can be fired quite easily once again (every permanent contract in a MAT has been on probation for 6-12 months, although I have left every job out of my own accord)?
