Drive a company into the ground (well, okay, mortgage its future for short-term stock price gain)? Get named President of another one. Bring along an exec who is later jailed for illegally arranging employment for a government official? Take over as Chairman and CEO. Have consensual, extra-marital sex with an opposite sex executive, though, and you’re out on your ass.
Condit was renowned for his affairs during his tenure (his second wife had been his secretary, and it was well and widely known inside the company when he moved into a hotel when his third marriage (to his cousin) was falling apart), so I can imagine only that somebody decided Harry must go. I’m able to infer some entertaining irony at the notion that maybe it was the ethics code that Harry made everybody sign that made his extra-curricular activities a bootable offense.
