The US really is a 'workaholic' culture -- it's amazing to see other developed countries and how their working culture operates. In America, most people average 2 weeks of vacation a year -- sometimes a little more, sometimes a little less. Regardless of the time, in most positions, it's a hassle for everyone but you, to take that time. Most cant take both weeks consecutively, and many are 'on call' so to speak during said vacation.
Other places, like France, have WAY more vacation time earned per year that is EXPECTED to be taken. In my research into MBA programs, it's fascinating to talk with other potential candidates from places such as France where they have this absolute fear of working in the states due to the lack of 'you' time you're 'allowed' to have. Coming from their working culture, I'd be horrified too.
