An employer’s arbitration agreement said that the employer and employee agreed to arbitrate all claims arising from the employment relationship, including class action claims and in the next sentence stated that the employee waived the right to participate in any class action lawsuit.  This decision holds that the agreement unambiguously required the parties to submit class action claims to arbitration.  The waiver sentence waived participation only in lawsuits–which means court actions, not arbitration.  The employer did not waive its right to compel arbitration by arguing in support of its motion to compel arbitration that only plaintiff’s individual claims should be submitted to arbitration.  The parties disputed the meaning of their agreement.  Arguing that dispute in court did not waive the right to compel arbitration.
