April 24 is a date of your diary (if you have a diary - surely you must have some sort of planner, regardless of how awful they might be...). NUT - a teaching union (but not the only one) - are getting its members to strike.
It's the first strike for twenty years, and is happening because the teachers are fed up with their pay. Apparently the government are stopping teachers' pay being affected by inflation. Unsurprisingly, they're not happy. You see, people want money if they're going to be subjected to chlorine gas.
But never mind what the teachers want. What does it mean for Temple Moor? Well, we've had a tip-off that about thirty staff are NUT members. This isn't a majority, but it's a fairly substantial amount. However, it's unlikely that Temple Moor will be shut (BSF disaster pending). So you can expect supply teachers to descend en masse.
Update: Apparently they can't hire lots of supply teachers. A day off is looking very likely indeed, which can only be good news.
