4 Day Week?

So apparently some schools/colleges/universities are experimenting with a 4 day work week. Why? Not for the pleasure of the students or the dismay of parents (who need to find extra childcare),no, they're trying to save energy and gas costs! It makes sense really. A day off for school buses and lights and computers etc. Hmm, but doesn't that mean they have to shorten the holidays? And wouldn't that mean being open for the same amount of days over the year anyways, even if days were longer to begin with? It's a good idea regardless. I'd love to only work 4 days a week (if just for the opportunity to sleep in for an extra day!). It's Friday, so technically in that other world I'd have the day off...
