We get two weeks starting and get three weeks after five years. I came in with two others (including my boss), and we negotiated for three weeks since we each have 10+ years experience. The extra week doesn't accrue, though, so I don't get it paid back to me if I leave.

How many years of experience do you have? If you have moe than five, I would try to get an extra week. I thought it was funny that our company was only giving two weeks of vacation when all the new hires had lots of experience.
