Who takes care of the caretaker's daughter...

Most of the local schools will be closed tomorrow because of strike action, No, it's not the teachers who are striking - it's the caretakers and the canteen staff. So how come the schools have to close? There's been plenty of notice, so ample time for parents - or for that matter the schools themselves - to provide packed lunches for those who normally stop dinners. And surely schools can survive for a day without a caretaker - they don't usually do their work during school hours anyway. It all seems to be down to "health and safety" - in other words the fear of being sued if anything were to go wrong. I really think it's about time we started to take a rather more adult attitude to these matters.
