But in this context:
> Baker's compensation has been inversely tied with performance
No reasonable person would assume that a person's comp structure from Company would be contractually bound to increase as Company's performance decreases. At which point, the interpretation of "tied" would swing towards generally accepted usage, i.e. "there's a potential relationship between these two things."
ameister14 suggested "associated with" would've worked better, and that's true. But "tied" isn't technically wrong.
ex. "John's salary is tied to performance - if the company is valued at over 100 billion, he'll get another 5% stock" etc.
or "bonuses are tied to performance milestones"
If you are simply observing that an executives pay rises while performance falls, associated is a clearer term.
