With so many people losing their jobs, the farewell email, letting colleagues and contacts know where you are moving and how you can be reached, has become common. Writing a really good one, whether it be funny, sad or just plain mad is an art form. Chris Kula, a receptionist at a New York engineering firm, wrote: "For nearly as long as I've worked here, I've hoped that I might one day leave this company. And now that this dream has become a reality, please know that I could not have reached this goal without your unending lack of support." In May, lawyer Shinyung Oh was let go from the San Francisco branch of the Paul Hastings law firm six days after losing a baby. "If this response seems particularly emotional," she wrote to the partners, "perhaps an associate's emotional vulnerability after a recent miscarriage is a factor you should consider the next time you fire or lay someone off. It shows startlingly poor judgment and management skills — and cowardice — on your parts." Let's hear the best and worst goodbye emails you've seen.
