One of the jobs that I worked for awhile had a bunch of old timers waiting for their pensions to be ready and newer people who only lasted a few years, with basically nobody in between. The old timers seemed weirdly surprised that everyone who didn't have the same heritage/grandfathered in incentives and benefits didn't want to stick around. I got to watch the tail end of the transition from the old engineer-run company that all the old guys talked about, to one run by beancounters who stiffed people on raises, bonuses, and promotions when times were good, and had plenty of layoffs when times dropped to ok. Thanks Jack Welch. I left pretty much right after my 401k match was fully vested.
