Well, the whole point is that courts won't weigh in, because of the arbitration agreement.

I took a negotiations course at university, and there was a section on arbitration vs the courts. There are plenty of good reasons to go with arbitration (employment contracts are not amongst them, though).

The one thing the professor highlighted was that if the arbiter was fundamentally unfair (e.g. civil rights violation), you're screwed. You can't then go to the court and make your case. There's no appeals process, etc.

I'm guessing there is no notion of "precedence" with arbitration, this being one of the reasons.
