"rethinking employment" was a clever way of "firing someone who cannot take direction".

If you're suggesting a manager sometimes needs to self-reflect, sure, but a good manager does eventually have to make the call that someone isn't up to snuff.

There are several people in my department who probably should be "rethought" or let go, but management is too soft to make the call. It's actually more harmful to several, who could easily move on to other roles.
