For a decade, companies of all sizes embraced the idea that allowing employees to work from home would make for more happy, productive workers and, at the same time, save companies money on the cost of office space.

Now, Yahoo! is reversing course. Its new chief executive Marissa Mayer is ending Yahoo!'s work at home program in June, according to an internal personnel memo obtained by the Wall Street Journal. Sources within the company tell the Journal that the directive not only affects those who work at home full-time, such as service representatives, but those who may work from home just a day or two.

"Speed and quality are often sacrificed when we work from home," reads the memo to Yahoo! employees. "We need to be one Yahoo! and that starts with being physically together."
