I've worked in a diverse range of schools and what makes or breaks them is nothing to do with OFSTED or exam results, but the support systems within the school.
I finished to prioritise my own DCs a couple of years ago. They needed more of my time than I could spare while functioning as a decent teacher.
I was finished off by:
Back covering, having to justify everything
Data/ target culture, heap of bullshit based on inflated meaningless SATs data
Whingy, uncooperative parents. Sadly even when senior staff know that the parental complaint is a heap of bullshit, you have to play the game and waste hours trying to appease them and evidence why you haven't been bullying the little darling who told them a half/ quarter truth.
Lack of resources. Having to fund classroom resources yourself or be hung out to dry by SLT because there was no glue/ pens etc
Constantly replanning and changing the curriculum. Constant new initiatives.
Double marking, parricularly when you write more than the student.
Restrictive curriculum forcing students into lessons they aren't suited to, in larger classes with no support.
Constant observations from collegues/ SLT/ accademy trust/ OFSTED
Everything is a battle for survival. Ultimately the survival of the school is fragile due to the target cultures. The fear of competancy procedures and the relief that the knives are out for Miss X not Mr Y.
It wasn't the behaviour in itself. Low level mass disruption is harder than isolated significant disruption. Most classes will have challenging individuals, but what swings it is if they have a willing or resistant audience to feed or ignore them.
Generally, I loved the kids. I loved my subject. I frequently felt that I was doing something worthwhile and beneficial to society which was what attracted me to the profession. If the cultures change by the time my DCs are older, I could face a return. It certainly isn't sustainable as it is.
I can't vouch for other professions. I know many of the cultures negatively affecting teaching also affect a multitude of other professions, but teaching does have a particularly toxic combination. Over half the work is done outside visible hours, and it's that outdated perception that make teachers outspoken about the difficulties even though they aren't particularly unique to teaching.
I haven't met a genuinely happy, satisfied teacher for a long time. That's since 2010 when a massive change occured.
I love reading with my DS's class. There's such a cosy veneer to it. I can pick up some of the undertones from my list though, and no state school is totally immune to it although some have tougher cultures than others.
