Pah, not much teacher bashing, there are threads all over the place, one about spelling (hilariously with bad grammar and spelling in the OP), one about school asking for money, just right now. There are hundreds in AIBU alone.
Lets be honest, most teachers want the kids to come to school and obey the rules, get on and learn. I think uniform has some good aspects but it does cause issues in some cases, when too draconian.
I agree that heads of failing schools often introduce new uniforms to no avail, its part of the corporatisation of schools a rebranding exercise, and yes sometimes can have an impact, but not if it happens regularly.
Personally I'd opt for a dress code, but I don't actually see that happening any time soon. I'd really like our 6th form to have one just to cut down on the fashion parade element ( and yes even when they can wear their own clothes there is that).
Lets face it, uniform isn't going anywhere soon, parents know what the rules are, shoes, hair cuts etc. Lots of work places have rules like this so its good for kids to get used to it. I've known parents plead poverty and scream blue murder when told their child can't wear those shoes, a good example was last year, boy in Nike Air Max black trainers Dad said he couldn't afford any more. Well don't spend over ??100 on trainers and buy shoes and trainers for less!
