To whom it may concern:
I am writing to inform you of my resignation from the position of Acting Junior Vice-Assistant to the Deputy Director of Marketing with immediate effect. I seem to recall something in my original contract about a thirty day notice period but in the spirit of agile management and notwithstanding the fact that I wiped my arse with said document a couple of months back, it’s probably best for all concerned if I slip off quietly into the night.
Go on admit it. You’d love it if I genuinely slipped off into the night. You probably wouldn’t complain too much if I slipped off noisily, say, from a fourteenth-floor window but in the famous words of Mick and the boys…you CAN’T always GET what you WAAAANNNNT.
