While the average American is lucky to get 11 vacation days from their employer each year
Doesn't this also decrease if you get sick?
I got properly ill the day before I went on holiday, and was out for about a week. All those sick days didn't count against my vacation days.
Furthermore, my vacation days are (to an extend) transferable, which meant I had 31 vacation days this year. That just seems normal policy here (25 vacation days is fairly common in mid-range jobs).
