While 1-in-4 workers work from home at least a few hours a week, a growing number of companies are now rethinking their work-at-home policies. For example, Yahoo recently issued a new “no working from home” rule, which says that all employees must now come into the office or quit! Also, Bank of America decided last year to require certain work-at-home employees to come back to the office. And Zappos, the online shoe retailer, is enforcing a new rule against working remotely.

Why the change of heart? In Yahoo’s case, their director of HR says it’s all about encouraging more collaboration because face-to-face interactions are a proven way to foster creative ideas! As a Yahoo memo puts it, quote: “Some of the best decisions and insights come from hallway and cafeteria discussions, or impromptu team meetings.” And that stuff can’t happen when people are working at home!

That also helps explain why people who work from home are the least likely to be considered for promotions, since bosses tend to only promote workers they see and interact with every day. But despite that, there are big benefits to working from home. Employees are happier, they’re less than half as likely to quit and are at least 13 percent more productive than office drones!

So, what do you think? Should more companies let people work-from-home, where they can be more productive? Or is it more important to work face-to-face, where employees can collaborate and interact?
