Here is what happened.
A meeting showed up on her calendar scheduled in 15 minutes. Two ELT members and the GM HR were there. Her first thought was transition plannng to become the company's CFO.
Instead she was told that she was being held accountable for a bad year. Two ethics violations by two of her managers, horrifically wrong price forecasting, and failure to close on two dispositions the company now regrets were not accepted. To be fair, these were really not her fault, but they did occur under her.
What they did not say was that they had a Golden Boy they wanted to develop up close and she was in the way.
She was given the red or blue pill choice. A demotion to a manager in Treasury, or a $14.3 million severance if she resigned and agreed to not sue. She left.
