Yep "quiet firing" I think is the new term for the old practice of forcing people out slowly by not giving them pay rises and making their existing position uncomfortable.
The correct term is "constructive dismissal".
the legal term is constructive dismissal, and that term has real weight in labor disputes
I wouldn't worry about the people who quit and leave. I'd worry about the people who quit and stay.
I agree, but an actual RIF would probably be less devastating to morale.
True, but there's a major difference between who leaves. A well-implemented RIF would eliminate many of those who prefer a Return to Office. So - for them - this is a better alternative.
