Listening (again) to teacher friends (again) and school children (again).
Anarchy in the classroom, shouting, swearing, children walking out and running around the school, back breaking workload, constant, contradictory criticism, abuse from parents ( and from managers - many of whom are not teachers) no resources, children destroying the resources that do exist, heating / lighting/ IT continually failing, marking too heavy to carry...constant pressure to "achieve" results that are not in any way under your control, low pay, children who want to learn being denied the opportunity to......
Surely these conditions would not exist if teachers didn't collude with keeping them in existence - not all schools are like this. Why don't teachers simply refuse to go along with it? The children that are stuck in schools like this are not being given a fair chance in life, even the really naughty ones are only children, and deserve to be in a system where they can be disciplined and trained, and educated.
I know its hard when you are working 80 hours a week and have no time to think about it, and when you have a mortgage to pay. I've been there. But with hindsight, I should have simply refused to put up with it, long before I did.
More teachers should leave!
