A Day Without Women

I've been tangentially hearing about this...and I can't say that I know what it is exactly. But am I wrong, but isn't a day without women in the workplace essentially a return to American norms before the 1940s-50s?

I read about a school that will be shutting down for this day because the women teachers won't be working. I wonder how the moms of the students will feel.

Also - as a general rule - for any of those considering sitting out a day of work (for whatever reason), I encourage you to wikipedia Wally Pipp.
