Three day work weeks could be a reality if Mexican billionaire, Carlos Slim has his way.

Carlos suggests that three day work weeks would work, if we worked 11 hours per day, and until we are 70-75 years old. Is that an even trade?

Slim has a good point, stating that four day weekends would give us more time to relax. While the thought of working a compressed work week seems to be popular with American workers, there haven't been any large companies adopting the schedule.
