Jamie Dimon is in a world of hurt. JPMorgan just got hit with a $13 billion settlement, which even for America's biggest bank is an unwelcome development. And yet, Dimon seems to be coming out alright -- there's little indication that he'll be forced out for presiding over a company that committed violation after violation. What's more, his employees don't think he's doing too badly either, giving him a 78 percent approval rating on the career Web site Glassdoor.com.

Turns out that's about an average score for most big companies. Browsing through the rest of the Fortune 500 gives us an interesting picture of where CEOs stand: With a few exceptions, the ratings tend to correlate with general consciousness of popular consumer brands like Twitter and Facebook. (Warren Buffett did come out with a 100 percent rating, but with only six reviews, it's probably not statistically significant.) They definitely don't correlate with how much a CEO is paid -- some of the most popular don't draw a salary at all.

Oh, and Microsoft CEO Steve Ballmer is less well liked than most.

Mark Zuckerberg, Facebook, 97 percent
