WebProNews has 42% of Workers Streaming Video in the Bathroom with their Smartphones. So you can bet at least 25% of those are on FB. It's safe to say that Smartphones are stealing at least 10% a day of the average american office employees time. Take 10% out of GDP and you have a very big number, its only a mater of time before business starts to jam 3G/4G at work. You don't need that to take calls. And they can track you if you use their wireless. Billions if not trillions are being lost to social media at work...I think employers are too trusting of their employees. Because they be screwing them big time!
