What it is
Arbitration clauses replace court for most employment claims, with a chosen provider, a fee split, a limits-on-discovery rule, and a waiver of class action. Some claims are carved out: workers compensation, unemployment, and sexual assault claims in several states.
What to do about it: Read the clause before signing, and check the carve-outs and the fee-shifting terms. A clause you signed at hire is the clause that will be quoted against you at separation.
