That one of the key people who knows how our technology works, how to improve it, and how much of a failure the current “upgrade” really is (engineering forced this “upgrade” without talking to those of us who know) will be handing in their resignation to join the competition in a matter of days.

I’ve already drafted the resignation letter.

Similar experience. Got in a bad accident when I was 15, entirely my own doing. That’s when I learned that some mistakes and their injuries are permanent.
