> What you can't do is having a Musk style temper tantrum and fire someone at will because you feel like that.

What about if you just don't feel they are a good fit anymore, even if you can't show why based purely on numbers.

Is any amount of advance notice sufficient to allow that?

The problem with “even if you can’t show why” is that it often means wrong gender, race, religion, political affiliation, drinking club, etc. A better question would be whether you could articulate what change you’re looking for and show that this standard was clearly communicated and applied to the entire team.
