Yes, that's correct. The math department has been as flexible and supportive as they can possibly be. They won't let me be on unpaid leave again only because the university won't. However, it's not like the mathematics department at UW has a lot of money just laying around. I don't think they have even a single position that is paid for by an endowment. It's very different than other departments I've been at. I was Harvard University's math department for five years, and they had far more discretionary money than UW math; also other organizations on campus such as Computer Science have received significant donations. The mathematics department's money comes mainly from the school allocating funding in exchange for teaching many important courses.
