Re: why is it your problem?
My wife is an elementary school teacher here in France. If you think the Education Nationale has on-call IT techs for hardware issues, I have news for you my friend.
Nobody cares about the equipment, nobody knows why the WiFi isn't working and if a reboot doesn't do the trick, the computers stay unused until such time as I walk in to check what is (or isn't) going on. If I get the things working again, everyone will be happy until it all goes pear-shaped again a few weeks later.
The younger, new teacher generation isn't all that better because now they've grown up on mobile and skipped the formative years of faffing around on school equipment or a home PC.
But there is light at the end of the tunnel : my wife is planning on retiring in four years. So I have at most four more years of school IT support to bear, and then I'll be done with it.
