Me, I'd worry about the person whose most loyal employees were bad. It would mean they don't provide the kind of workplace where good employees stick around. The number one reason people leave jobs: they don't like their boss.

There are a lot of technically brilliant people who aren't looking to move for a 10% pay rise (unless they are grossly underpaid - sheesh, don't underpay your people). Great people will stay for a good boss (see above), a happy environment, a degree of creative freedom, opportunity to work independently, the chance to extend their skills, etc etc.

It's true that bad employees generally don't quit, though.

[Edit: Don't believe me? Ask Pixar what their staff turnover rate is. Is Pixar full of bad employees? Methinks not.]

I'm not sure the intent was commutative (if a then b, but not if b then a)?

Your bad employees will be loyal.

That doesn't mean your loyal employees will be bad.
