I recently donated to the Red Cross through my employer, since they match employee donations dollar for dollar, and 50 cents on the dollar for retirees. I hear we gave $2.3M collectively, not including their matching, or the $1M they donated separately. But we’re huge, so that’s reasonable. (And I’m not mentioning them, since like so many other corporate employers, they don’t like employee blogging. Someday I’ll have to pay to retain my privacy for this domain, and cut down on spammers).
