If people really want to play video games or surf the web all day, they’re perfectly capable of doing so from their desks at the office. In fact, lots of studies have shown that many people do exactly that. For example, at clothing retailer J.C. Penney’s headquarters, 4,800 workers spend 30 percent of the company’s Internet bandwidth watching YouTube videos.* So, coming into the office just means that people have to put on pants. There’s no guarantee of productivity.
