At the point where I had ~5 years of experience I was put on a variation of PIP for being overly negative about a (new) project's direction and feeling that our efforts were very misguided. My manager provided some training items on soft skills, then I left the company a few months later of my own volition. While I still feel that the project was fundamentally flawed, and last I had heard it was scrapped shortly after I left, I do get the sentiment and have used it to at least better gauge when/where to critique and try to provide insights going forward.
