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 currently have 7 weeks off/year plus 10 holiday days. No way I'd take all of that with the unlimited plan.
