How many hours a day and a week?

What the law says

• Normal working time cannot exceed 8 hours a day and 40 hours a week; a collective agreement can set less (Art. L. 211-5).
• The absolute maximum is 10 hours a day and 48 hours a week (Art. L. 211-12).
• In some sectors set by regulation, 12-hour days can be allowed, as long as the week stays at 40 hours actually worked (Art. L. 211-12).
