Saw a thread on Hacker News discussing this article:
There are a lot of solid points there but I particularly like (have seen) this one: "An organization populated by a majority of incompetents has less than zero net-worth : it is able to destroy other adjacent organizations that are not similarly populated".
"Fire whenever you get away with", creates toxic workplace cultures over time, though management will be blind by it until the axes finally grind themselves. Studies show that such culling actually lowers productivity and innovation too, as it creates really bad group dynamics where everyone in the group vie to be #1, do the "best" type of work, avoid necessary risk-taking, creates blame-culture, dissolves trust, team-work, mentorship and constructive diversions, etc.
Otherwise these read like a summary of common workplace experience. Management just doesn't hear about it, since everyone is punished by pointing out flaws or taking initiative.
