Sometimes you hear about companies that let people work four days a week, which sounds great.  So THIS sounds even better.

   

CARLOS "SLIM" HELU is the second-richest person in the world . . . he's a Mexican businessman worth $80.3 billion.  And he says the future of work is a THREE-day work week, and a four-day weekend.

   

But there are two catches.  One, you'd have to work about 11 hours a day all three days.  And two . . . you'd be expected to work until you're 70 or 75, because we'd need more people working total, to make up for all the lost hours.

   

Slim says, quote, "With three work days a week, we would have more time to relax, for quality of life.  Having four days off would be very important to generate new entertainment activities and other ways of being occupied."

   

For now, Slim has started incorporating a "lite" version of this at the Mexican phone company he owns called Telmex.  People are eligible to retire before age 50 but if they want to stay on, they can work four days for full pay.
