The teacher obsession on this site baffles me. I just don't see it anywhere else. And I am a teacher, so I know a lot of us!
Many mumsnet teachers seem determined to take every opportunity to point out how they've 'never worked harder', are 'on their knees' and have been 'thrown under a bus with no ppe'.
Many mumsnet non teachers seem determined to point out at every opportunity that teachers are 'workshy', 'make everything about them' and have way more time now than we did pre Covid because we're apparently sitting around in our pjs all day.
Yet, in the real world, everyone just seems to get on with working hard at whatever job they do, respecting that everyone else is doing the same. It's like a parallel universe.
In answer to the question I would imagine, in all probability, that there are a small number of teachers who aren't committed to their jobs but that the vast majority are. Which I think is also true of every single other profession too! But it's more singling out of teachers as a special entity which we just aren't. For either good or bad reasons. We are one of many professions doing our jobs, same as everyone else.
