You can't get "specific performance," where the court physically forces you to uphold the agreement. But it is enforceable in that Yahoo could sue for damages.

You can't get "specific performance," where the court physically forces you to uphold the agreement. But it is enforceable in that Yahoo could sue for damages. The damages probably wouldn't be all that high though. It is more of an issue when the employment is something unique. Like a start athlete or movie star. You can't just find another person to play Tony Stark in Iron Man 4. But there are plenty of people who can be a Yahoo executive, relatively speaking.
