So that's why I'm not working right now

I had no idea this was the history of NYC’s February break:

Here’s a piece of city schools history: The midwinter break enjoyed this week by New York City public school students and teachers began as an energy-saving measure imposed during the oil crisis of the 1970s. It remains a part of the schedule because of a budget deal between the city and the teachers’ union.

I had no idea such a thing as February break existed before coming to college on the East Coast from the midwest.  I always assumed it was to keep the ski industry in New England doing well.
