i used to work for this headmaster. we were in the inner ring of brum, and they'd imported him from Wales. they used to believe that headmasters were a bit like bloodstock, and to improve the line - you didn't get someone who knew the kids - you got someone who'd been a whizz amongst the sheep rustlers.

so the guy sat in his office , not daring to walk the corridors of his own school. making up rules we couldn't enforce. making jokes in assembly - he'd got from the readers digest, and we couldn't give a shit about and the kids couldn't understand.

laughter is the best medicine when you're confronted by an idiot.

Steve - the legal entitlements that you speak of have been unenforceable for generations. the agricultural workers are dependant on the gangers for work. the farmers are having their balls squeezed by government regs, they are squeezing the gangers.
they are vulnerable. they have an insurance card etc. but that is their situation - always has been. along come the seasonal workers. it used to be their wives and kids and traveller families. then along comes the economic migrants. they work for even less.

there are no bad guys. its what monkeys do. if you're not a monkey you won't really get it.
