A lot has changed in the past 10 years. It's been almost a decade since IBM lead a revolution to shift from a centralized to a remote workforce. By 2009 remote work was a corporate perk for most -- 40% of IBM's 386,000 global employees were working from home. No more wasted commutes. More flexible family time. Pet your dog while you're on the conference call. It's worth noting that IBM banked about $100 million by cutting 78 million sq. ft. in office space.
