Jessica Lessin of “The Wall Street Journal” says Apple has launched a program dubbed “Blue Sky” that lets employees take two weeks to work on projects outside their normal responsibilities.

It’s similar to Google’s 20% time, which lets employees spend 20% of their time on side projects that could end up helping Google, according to “Business Insider” (http://macte.ch/hL1N1). Lessin says “Blue Sky” is a lot different than Google’s approach, as it’s limited to a small group of Apple employees.

However, she says it shows Apple’s culture is changing gradually under CEO Tim Cook. “The hope is to keep Apple’s employees at the company longer,” says “Business Insider.”
