An article extract about Satya Nadella's appointment as CEO of Microsoft:
“Microsoft chews up and spits out new hires in senior roles,” said Charles Fitzgerald, a former strategist at Microsoft. He added about Mr. Nadella: “He knows where the bodies are buried.”
What does "bodies buried" mean in the corporate world?
If new hires were spit out, then they are no longer in the organization, so why the word "buried" to describe them?
What is the significance of a person knowing where the bodies are buried? How does it give a person strategic advantage to take on a senior role in a company?
