I can.
I was stuck in a job I hated for over a decade, and not only that, I was the guy on the team doing the shit jobs no one else would do because many of the older, tenured people didn't want to work weekend hours ever.
I remember the slight panic in my boss's eyes when I put in my two weeks, but it wasn't half as sweet as my former coworker's panicking when they realized that they'd have to figure out how to do my job without my help. One even had the balls to say something to me about selfishness.
You see, they'd also declined my offer to train them on the functions I was involved in and the items I created.
Glorious.
