Can I ask you about occurrences of fence post errors?
There was a very important eng who was basically a sole contributor on a difficult component in a system. He announced his retirement date well in advance, but after the bonus payout period. HR terminated him early, denying him the bonus and leaving the team to scramble and organize a mini-summit to do knowledge transfer. The team itself had no control over the date. I believe it was a similar company.
