I've been a teacher and there's a lot of issues that trickle down to the classroom from politics, OFSTED, academy chains and management. The classroom teacher tends to be the visible face of this.
Not all teachers are equal. Some are great and some are... not.
The Covid years did not do the profession many favours. Particularly in the first lockdown, standards were variable to put it mildly. My DCs were at the same school. One teacher put a lot of effort into planning accessible work and did a weekly quiz to keep in touch, the other phoned once and sent out lesson plans that would not have been acceptable to have left for a supply teacher and of a poor quality that could not be printed. This was for my child with recently diagnosed SENs. There was zero concern that he wasn't capable of completing work for half a school year.
Beyond that period, schools keeping parents at arms length has been very damaging. Seguing into SEN provision, it doesn't have to mean expensive or time consuming measures. It would have cost virtually nothing to allow DS to use a PEN in line with the recommendations from the specialist who diagnosed his dyslexia/ dyspraxia. This didn't become apparent until we finally had an in-person parents evening halfway through year 6. It looks like the teacher would have sent him off to secondary school with no experience of using the appropriate writing equipment 🤦♀️ He also has a laptop (paid for by us) that he should use to prevent fatigue and the first teacher of the year was unaware of this adaption despite having previously been the SENCO that I had communicated with about it in a previous school year.
This doesn't mean I hate teachers, but I am jaded about poor practice at present!
There is a vocal core of whinging MN teachers who do not represent their profession well, again especially through the Covid years. When I taught, there was normally a small minority of whingers in the corner of any staffroom who seemed to have lost any love of anything connected with the profession and often seemed to count the terms down until they could claim their pension. They're not representative of the masses though and have probably reduced in number through recent years of performance management.
While teachers often face unrealistic criticism, sometimes there is justified or constructive criticism and they're human not superheroes. I have encountered a few that will talk to anyone like a disobedient juvenille (as a petite woman, if I made the error of wearing something that blended too well with a uniform, I copped this on many occasions!) It's an attitude that wins no friends!
As a profession, pretty much everyone encounters teachers as children/ parents so it's easy to form some form of opinion about it.
Most teachers do a decent/ good/ great job often in challenging circumstances though. I still know many and while the politics wears them down, they believe in what they teach and their young people.
