It still hurts to see a decade of work stolen. I realized too late that I was hired to do the heavy lifting for others who took advantage of me. (Those who are adept at managing up but made little contributions.) The real disappointment was to see former co-workers who passed off my work as their own because of their lack of competency just to survive the ranking. If they go that then have the decency to acknowledge me when they published or present my work.
Yeah, I know some people only show up for the paycheck. But if you care about these things, then don’t work here.
