Heh. Man I'm glad I talked my VP down from the cliff. He honestly thought it was a Good Thing.
I currently have 7 weeks off/year plus 10 holiday days. No way I'd take all of that with the unlimited plan.
Wow. Are you in the US?
I'm in the US, at a law firm, and after the first year, every year is 7 weeks vacation + 10 holidays just like this. I'm glad, because they told us we had an unlimited vacation policy that I do not use and on the books in the first year we're only supposed to get 7 days.
I gotta say, after watching his chat at Google IO, I want to read that book now.
I worked at a company with "unlimited vacation" and I took on average 5 weeks of vacation per year - so it does sometimes actually work.
Likewise - I'm floating around 4 weeks taken in the past 365 most of the time (which is more than any previous employer would give) and I never have any complaints or issues. My boss doesn't say anything and just approves each one.
