OK so school pays... starts an ongoing "let's hammer the school" culture (I once had a parent present an itemized bill of everything her kid had lost at school - funnily all found where her kid who couldn't be arsed to bring anything home had chucked it)... school has to start taking out insurance policies against these incidents.... can no longer afford books and resources. Cue outcry on here over that.
Oh no I forgot - then the teachers will personally prop everything up more than they do anyway and just buy ALL the pencils, paper, gluesticks, resource books for their classes.
Shall I add the incidents I've seen where I've seen colleagues sworn at, abused, insulted, physically threatened over property at school (usually just a case that the kid's chucked their coat down somewhere and not bothered to pick it up)... the mother who demanded the head searched every locker in school (and the head got into school at 6am one morning to DO this for a quiet life), who sent her husband effing and jeffing down to County Hall demanding an official LEA enquiry, who screamed at my year group partner for approximately 45 minutes.... object in question was a £3 pair of Asda PE shorts.... the woman I saw with her face 1inch from another head's face screaming in it.... the mother I mentioned (whose son had no sense of responsibility for his personal posessions - to the extent he couldn't be bothered getting his spellings out of his tray, and it was sheer couldn't be bothered, to take home - so mum came in every week to write his spellings down again for him) who collared me with an invoice for everything he'd "lost"... that funnily enough materialised on the top of the lockers.
You have kids together - accidents happen, things get broken - I've spent hours on my hands and knees looking for screws that put nosepieces or arms back on pairs of glasses so they're easier to repair (despite knowing opticians will do this for free anyway). Trouser legs get ruined with football sliding tackles, bookbags get holes in over time - and kids reach out and grab and pull, sometimes aggressively, sometimes out of sheer curiosity (I'm forever nearly being garrotted by kids just wanting to get a closer look at necklaces I'm wearing)... things happen.
And anyway - there are no such thing as NHS frames anymore - you get a voucher, if you want to top the voucher up and pay more (how I coveted those pink frames with a lil bow on the top and sparkly bits when I was a girl) then you do so. Opticians are generally incredibly good at wangling kids frames through for as little as possible as well - I know ours was forever doing it when I sat on me specs as a kid.
And yes hocuspontas - I've seen schools expected to pay for that too... and teachers screamed at for it.
