Well, for example, the only rule a schoolneedsregarding hair is that, if it's long, it has to be tied back (especially for any lessons with a practical element.) Anything else is petty bullshit. Having bright green hair has no effect whatsoever on their ability to do sums or analyse a paragraph.
No it doesn't. But you know what, in life there are rules. I had a nose piercing when I started teaching. Lots of schools have a no unconventional hair colours, no tattoos on show and no facial piercings as part of the dress code. I could decide 'eh this is pure bollocks like I'm still a good teacher even if I came in with 173 rings in my eyebrows'... or I could be a sensible adult and understand that workplaces have rules.
School uniform which is both expensive and poorly-made, covered in logos and only available from a particular shop, is definitely an indication of a bad school - and a school which is trying to 'improve' by getting rid of all the disadvantaged students, usually.
Sweeping generalisation there.
Some uniforms are completely crap in my opinion.
However, the schools near me who have gone down the route of prescribed uniform have done so because they got fed up of parents buying leggings as trousers, trainers as school shoes, short tight jersey skirts as school skirts etc. (Mainly from thr same parents who send them in with red hair, dip dye etc) usually with the justification of 'my mum says it doesn't matter if i don't follow uniform becaude it's shit anyway'.
And then we get back to the problem some of these schools face: a longstanding culture of 'only follow rules ypu fancy. If thr teacher tells you to do something you don't want to, refuse and I'll come in and kick off'
Put it this way, I was assalted by a student once as he was verbally abusive to his peers and trashed my lesson. Mum came into school to DEFEND her child because 'he didn't want to take his coat off. He wasn'r ready to sit down. What difference does it make where he sits?'
It's very unhealthy to teach children they must obey without question and 'respect' pointless bullying
Following rules you don't like isn't pointless bullying. The fact you think it is probably is telling.
I expect my students to follow my rules, even if they think they are pointless. If thry wish to discuss them with me, we arrange to do that. If students feel there is a collective issue, we have student leadership bodies who represent them.
We teach them how to raise issues appropriately because in life just saying 'narr i don't think so' doesn't get you too far (and it's that culture which leads schools to become sink schools).
and a good idea to demonstrate to them that you as a parent have got their back when they are being treated unfairly
Unfairly? Or just being asked to follow a basic set of school rules you might not personally prefer?
At the moment you are starting to sound like the very person who is part of the culture of 'teachers give rules you don't like. Don't you worry kiddo. I'll tell them'.
