You are correct, grey whiskers.
Another case in point is Yahoo’s Marissa Meyer and ex-CEO of HP Cara Fiorina.
There are several others, but that is what gives rise to corporate raiders like Carl Icahn. Icahn recently took over the Trump Taj Mahal (The Donald has been long gone, only the name is left) and is in the process of shaking up the dead wood management.
And before HP, there was Lucent.
To this day, I still can't believe what management did to Lucent. For most people who aren't familiar with how Lucent came into being, the "core" of what became Lucent was AT&T's legendary Bell Labs.
Bell Labs invented (though some claim "reverse-engineered," from Roswell, NM) the Transistor. Unix (and eventually Linux) sprung from the fertile minds in Murray Hill, NJ!
And Carly Fiorina helped ride Lucent into the ground.
