A survey released today by Microsoft (NASDAQ: [[ticker:MSFT]]) says San Diego is the best midsize city in the United States for remote working. The nationwide survey commissioned by the Redmond, WA, software giant found that U.S. employers generally support remote-working programs, although just 39.4 percent have a policy that details how their employees can work from home. Microsoft says interest in remote working has been spurred by higher energy costs and the current economic crisis.
