Thirteen-year-old Aaron and twenty-three-year-old Derek start jobs with the New York Yankees. They both sign contracts and commence work one month later. Both contracts specify parties, terms of employment, salary, and job responsibilities clearly. One month later on their first day of employment they are both asked to sign a document that purports to compel arbitration of any disputes that they might have with the Yankees. In the document, Aaron and Derek, both agreed to comply at all times with and to be bound by the constitution and bylaws of Major League Baseball (MLB). They agree to refer all disputes to the MLB commissioner for a binding decision and to release the Yankees and others from any related claims. Nowhere in the document did the Yankees agree to do anything.
