I'm a teacher too. I think part of it is we've just been expected to get on with it and we've had no choice but to put a brave face on, be positive, hold it together etc because we're literally the adult in the room. And whilst yes we all feel burnt out etc and we should take it easy that isn't actually possible because it just keeps ramping up. Ofsted back, exams, ever increasing workload, kids and parents more needy and comfortable to email you and expect rapid responses about every little thing and not really having any choice but to keep going no matter what.
When you're doing that for the better part of two years whilst meanwhile if you needed to nip in the chemist to pick up a prescription you'd find a queue outside in the rain because only two people were allowed into a chemist that's as big as your classroom yet the staff are on go slow mode and don't give a toss that people are outside getting wet it's a special kind of frustrating. I found lots of things frustrating because I was being made to act as if everything was normal at work whilst being made to wait, get wet, have shit service, deal with not being able to talk to a gp, see a dentist, etc because... covid. We've had to deal with really mixed messages and realities as teachers. It's fine it's just a sniffle, you'll be fine for our working lives v omg stay 2m away from me, you can't come in here without a mask, it's fine for us to let you get soaked in the rain etc in the rest of our lives.
The younger end of secondary are extremely needy and demanding and many of their parents are too, that's not to say I blame them or am slagging them off for it but, none the less it's exhausting. There's been no slack where I work. We've had ofsted, still pushing on with crazy targets, still pointless observations and book looks and so on as if covid never happened and therefore having to act like that yet I have to remember to allow slack and have compassion for everyone and everywhere else. I think I'm saying it's probably natural to feel a bit intolerant when you've had to pull your big girl pants up so many times and so far without a word of thanks and mostly just being slagged off from all corners.
