Stated several times elsewhere, I announced my retirement the Friday before Labor Day. My last day on site was the next Friday, though my actual retirement date was end of the month (way more than 2 week notice - told them to call me if questions - about my retirement, that is.) Anyway, I left my office clean and neat, files properly labeled and purged where appropriate, computer wiped of any personal stuff, (except my screen-saver saying "Those who think in inches and talk by yards should be kicked by feet".)
My parting gift was to leave all of my Hawaii posters and pictures still taped to the office carrels and neatly push-pinned to the cubicle divider cloth. I figured I wouldn't need them anymore and my cow*rkers might as well enjoy them in my permanent absence. At the time, we were in full "Last one out, turn off the lights" mode. So, I'm pretty certain those pictures were there when they finally figured out what they wanted to do with the office and attached lab space. (Actually they sold it all a few years later - always figured the "new guys" either loved or hated the motif - It's the romantic in me.)
I felt lucky that, at the department level (and even for the most part, the division level) I got along with most of the folks with which I interacted. My main reason for calling it quits was that I didn't wish to move to a new assignment - one for which I was not particularly qualified and one with absolutely no rewards (other than being "allowed" to keep w*rking.) My OMY syndrome was more or less instantly "cured" in my head and in my heart. It was the best thing that ever came my way at Megacorp.
I do still keep in touch with 2 people of the (literally) hundreds of folks I got to know there. Sad in its own way, I suppose. Still I left with very few regrets and I left on my terms and on good terms with everyone. If anyone there even remembers my name, I could care less if they thought I was a good w*rker, major achiever or all around good "company man." If half a dozen folks remembered that I always tried to get along and not push my way to the front, I would be most happy.
Wow! This brought back way more feeling than I thought I still had. Go figure!
Of course, YMMV.
