If you're a C.E.O., there are a lot of ways to leave your job, from abrupt firing to carefully planned succession (which may still go spectacularly wrong). In this final episode of our "Secret Life of a C.E.O." series, we hear those stories and many more. Also: what happens when you no longer have a corner office to go to — and how will you spend all that money?​

No, it's not your fault the economy crashed. Or that consumer preferences changed. Or that new technologies have blown apart your business model. But if you're the C.E.O., it is your problem. So what are you going to do about it? First-hand stories of disaster (and triumph) from Mark Zuckerberg, Steve Ballmer, Satya Nadella, Jack Welch, Ellen Pao, Richard Branson, and more. (Part 4 of a special series, "The Secret Life of C.E.O.'s.")
