A friend with a background in industrial-organizational (I/O) psychology was hired at Amazon a few years back and was shocked to discover the 10% turnover rate. As they shared, they took it upon themselves to find a better way to manage turnover and have a better performance assessment system. They implemented it and brielfy reduced turnover to 3%; until Bezos intervened and explicitly asked for at least 6% turnover. For someone with a background in I/O psych and interest in improving worker well-being, it was soul-crushing and they soon left. It appears HR is also helpless in improving conditions, the turnover goals actually came down from the top. It's possible this changes with Bezos gone, but I wouldn't hold my breath.
