Tomorrow, December 10th, is Day Without a Gay, where several activists in California are asking people to call in "gay" to work, not to shop, and to do volunteer work instead.
It's complicated - yes, it's good that people are coming together and organizing something without the stamp of approval of a real org. And it'll definitely attract media attention if enough people participate. But... this isn't really a market where labor has much leverage (what with there being who knows how many people ready to take your job if you get fired because of this).
Here's their volunteer opportunities page.
I'll open this up to you all. Do you think this is a good idea? Are you participating?
