If people do quiet quit… doesn’t it make sense? They can continue receiving a salary and fulfilling their job responsibilities during a transition period in their lives. Their employer gets their job responsibilities performed, perhaps to the letter, but it reduces churn / time-between-hires.
The one group of people that quiet quitting might not work for are executives, whose salary is justified by them being able to deliver outsized value, which it is hard to show up to work and do on autopilot.
