It is true that we (French) say "le burnout" but it does not mean we are not affected too, contrary to popular belief ;-) A few years ago, it seems that workers of ex-publicly held companies (France Telecom for instance) were the most affected with a few suicide cases that made the news. Recent studies said 2 workers out of 10 felt affected. IMHO, the white collars of big companies feel affected because they have to do more than before to stay in the international race in less time since they usually have 6-10 weeks of holidays per/year (no sick days). Having so many holidays is really challenging for an organization, especially in the summer, period of the year when people are off for 2-4 weeks. It means also long work days for workers. Personally i'd prefer to have less holidays and come back home earlier.

Having said that, on a yearly basis, white collars work much less than their American counterparts on average.
