Following Garcia v. Pexco, LLC (2017) 11 Cal.App.5th 782 as a correct statement of California law on a non-signatory’s use of equitable estoppel to compel arbitration against a signatory plaintiff, this decision affirms an order compelling arbitration of the plaintiff’s wage and hour claims against defendant hospital.  Plaintiff was directly hired by a staffing agency that paid her wages and with which she signed an employment agreement that included an arbitration clause.  The staffing agency assigned plaintiff to work for the hospital.  Plaintiff’s wage and hour claims against the hospital were necessarily intertwined with her employment agreement with the staffing agency and within the scope of its arbitration clause, so shewas equitably estopped from refusing to arbitrate even though the hospital was not a party to the employment agreement.
