It is not as simple as that. There are many countries in which the official work day is less than the real work day. As an example, in Japan no-one leaves before the boss leaves (so it can be longer than the official time).

Also, in some countries there are many people working for themselves (such as in small businesses). These people generally work more than the official time.

I had a family member work for 14 hours a week (10 hours saturday and sunday) while starting their own business (this went on for two years).

Small business owners break the law a lot and work more than the allotted time.
