I am doing long term supply at an ok school. Despite being 14 or so years in to teaching and despite having worked at more challenging schools in the past I am having trouble with discipline. Every lesson seems to descend into a game of whack-a-mole with low level disruption (banging on desks, refusing to be quiet etc) breaking out. You tackle it in one area, it breaks out somewhere else. I keep finding myself shouting as this generally gets them quiet (speaking at normal volume just gets ignored!). Anyway, I happened to ask a few kids who came back at lunch if this happened in other lessons. Apparently not! One student said (not at all in a snide way which made it actually worse): "I don't know why sir but they just don't have any respect for you". This hurt more than the hundreds of times I've been told to foxtrot Oscar! Is this something particular that happens on long term supply where the kids are not sure if you are a 'real teacher' or not? Hence after an initial honeymoon period the playing up begins? This has left me feeling quite dejected and thinking about getting out. ( Not that I'm really in), just doing supply gigs in the hope of something else coming along. There was a time when I thought I was good at this job!
