Not to step into a troll, but basically depending on the metric you take, it is either less or more (it's a big troll in France), so I prefer to think we work about the same.

But the office habits are very different, in France people leave the office way later than in Germany or the US (6 or 7pm), so it's quite a shock for some foreigners (basically our lunch break is longer, and our coffee breaks are shorter). You might have trouble getting a hold of people on Friday afternoon because they might take it off, and more and more on Wednesday (some people just take a 20% salary cut and spend one day with their kids).
