Yeah, i think it's a common situation in that industry. My first year I burned all 8 of my PTO days to get married and go on my honeymoon, I lasted 2 years there. I don't think that's because it's on the way out though, I believe it's just caused by the way your stereotypical engineer/company owner thinks, straight line correlation for time employed vs. salary, vacation, bonuses, etc.
The younger workforce seems to be for more transient than previous generations too. They are more impulsive, if they get slightly uncomfortable they just move on and find something else, it correlates to the article posted above about homebuyer remorse in the current market. I went back to real estate after my engineering job and worked largely with younger and first-time buyers, they mostly had new jobs and wanted Pinterest houses but didn't want to earn sweat equity. In my opinion a workforce more willing to change jobs and less willing to own or improve a home will contribute to more nutty market fluctuations in the future.
