Employers are also human, and prone to the fallible traps of responsibility that befall many people managers and executives, including but not limited too:

* not trusting your team to do their work and by extension questioning whether they are working "hard enough" (or dreaming of ways to extract more blood from stones)

* some flavor of impostor syndrome, needing to prove your value by making sweeping changes to the team process even if inheriting a successful team

* not having either the back bone or clout to question status quo, including demoralizing cultural habits such as stack ranking

There is a reason the majority of employers (including managers) are generally bad and the good ones are few and far between - it's human nature.

I'm reminded of Microsoft Japan piloting a 4 day work week and announcing in 2019 that the trial ended up increasing productivity by 40%. They ended up not making the change permanent. One small company in New Zealand - Perpetual Guardian - did the same trial in 2018 and saw the same effect, they made it permanent.

Most companies operate like Microsoft.
