I've never been "right-sized", when the right size was larger. Both times, I was let go because of gross mistakes that management had made, requiring a reduction in employees to attempt to arrest plummeting stock values. The last time, they had to hire two people to replace me, and I just found out from another previous employee of the same company that eventually they just gave up on my old territory. Seems they couldn't keep anyone willing to put up with what I had been putting up with.
I have to say though, that I was an idiot for staying as long as I did. They did me a favor by letting me go. My life improved DRAMATICALLY and immediately. Kind of like my previous marriage. I'm such an idiot.
