Cisco has just finished conducting a huge international study involving 2,600 workers and IT professionals from 13 countries. The survey showed 3/5 employees "believed it was unnecessary to be in the office to be productive". And this study wasn't skewed by lazy westerners looking to spend more quality time with the Xbox. 81% of Chinese employees and 93% of Indian employees felt this way.
76% of Brazilian workers also supported working from home and accessing work-related information on a broad family of devices. About half of employees admitted to working between 2-3 extra hours a day outside of the office. A quarter put in 4+ hours. More and more, people are coming to prefer the freedom of a home office.
Of course, there are still major concerns. Big businesses have big privacy worries, 57% of IT respondents felt that security was the major issue preventing broader adoption of mobile offices. The study neglected to mention any of the morale / health benefits of going whole days without wearing real pants.
