Janice Quilloin (plaintiff) worked for Hahnemann University Hospital on two separate occasions. Before beginning her employment on both occasions Quilloin signed an arbitration agreement. The agreement provided that both parties would be responsible for their own expenses and attorney fees for arbitration. The agreement also allowed the arbitrator to award any remedy available if the claim had been heard in a court. The agreement did not contain any provision on class actions. Quilloin later sued the hospital, the corporations that owned and managed the hospital, and their parent corporation, Tenet HealthSystem Philadelphia, Inc. (Tenet) (defendants). The district court denied Tenet’s motion to compel arbitration, and Tenet appealed.
