I was fired from a job I had had for 10 years. New Medical Director was hired and he took an immediate dislike to me for some reason. (I filed for unemployment and it was found I had been unfairly dismissed.) My replacement had already been hired, and I knew it a few weeks ahead of time. So I busily emptied out all my files of information that would help this new person do their job, you know, also they would have a “clean slate”. So, when I left, there were only a few personal items on my desk and a few files of generic information. The company had been going down hill for 2–3 years, and everyone in the department I worked in had left for greener pastures. The revenge: The entire company folded 3 years later. (The only good thing was that my friends that had hung in there until the end got some nice severance packages.)
