Noooo. They seriously only give 2 weeks holiday a year? that's insane.
Strangely enough, this doesn't seem to have a straight-forward correlation with yearly hours worked. Italians have about the same number as Americans, but 20 mandatory days and quite a lot of Catholic holidays. Koreans and the Greek seam to top that list, although I'm currently not a big believer in Greek statistics…
Plus an additional 6 "personal days".
That being said, I've yet to actually take a vacation day at Amazon, despite regularly getting automated e-mails about it from HR. I send a polite OOTO e-mail to my team and that seems to be sufficient. This may very from team to team and manager to manager.
