Wow, that really is incredible... I really can't imagine not being able to take a week of vacation for fear of losing my job...

Do you guys in the US get time in lieu? My job is 40 hours a week, and if you work longer than that, you can take the time off later. So working fifteen minutes longer every day lets you have another week off (paid) every year, in addition to the four weeks paid holiday you get.

And since holiday time accumulates, you are encouraged to take most of it every year.
