Facebook's Zuckerberg Tops List of Highest Rated CEOs

Mark Zuckerberg may not have the business savvy to propel Facebook's stock to soaring new heights (or even back up to its IPO price), but be that as it may, he ranked No. 1 on Glassdoor's list of the "Highest Rated CEOs" for 2013. The career's site gave Zuckerberg a 99 percent approval rating, but what does that mean?

It means his employees like him. A lot. Glassdoor's rankings are based on feedback from employee reviews over the past 12 months.

"CEO approval ratings are calculated similar to Presidential approval ratings; employees are asked: "Do you approve or disapprove of the way your CEO is leading the company?," Glassdoor explains.

It's essentially a pass or fail system, and the vast majority of Facebook employees gave Zuckerberg a passing grade. That's up from an 85 percent approval rating in 2012, though the lack of supplementary data makes it hard to analyze. Glassdoor doesn't ask any followup questions or provide additional insight about why employees approve of disapprove of their chief.

Meanwhile, Apple CEO Tim Cook fell to No. 18 with a still-impressive 93 percent approval rating. Like Zuckerberg, Cook is dealing with a share price that's below where investors would like to see it (isn't that always the case?).
