Whatever you think about mandatory arbitration clauses, they require consent. The First Amendment implies that people generally have the right to “petition the Government for a redress of grievances.” In other words, in the U.S. it’s fundamental that participants in mandatory arbitration have legally waived their right to bring the case to court.
When it comes to resolving employment-related disputes, many companies have determined that a resolution in arbitration is desirable. Ideally, arbitration is less expensive and more final. It gives the employee an opportunity to have grievances heard by someone other than management, and it gives the company a more private resolution without the risk of negative publicity.
