Think Progress reports on Treehouse, an online education company that only works 4 days a week. Company founder Ryan Carson was working 7 days a week on a new start up. He made a decision that life was as important as work and instituted a 4 day work schedule for all employees. Treehouse is one of Carson’s 3 companies that follow the 4 day work week model. Some experts think this kind of work model improves performance while working more (60 hour weeks) hurts productivity. Time will tell if more companies follow Carson’s model – if he can even sustain it with his companies. The first step is to try. Three cheers to Ryan Carson for remembering that life is not all work.
