In France most white collar workers have the "cadre" status that was originally only used for managers. It somehow means you are free to organize your work time under the condition to work a certain number of days per year (often approximately 218) and have your task done (or at least give the impression you've done at much as possible). The legal number of hours per week is still 35 (or more + RTT days) but the time you do over the legal number is counted as "overtime" only if your manager requests that you work more and that is very rare. In many companies the real work time is much higher but I can't give you a realistic global value.
