This decision holds that the trial court erred in not compelling arbitration in this wage-and-hour case.  The employment contract Gonzalez had with his direct employer, Nowhere, contained an enforceable arbitration clause.  Gonzalez also sued, on the same claims, nine other entities which could be liable only if they were his joint employers.  Since the liability of the nine alleged joint employers all depended on Gonzalez’s contract with Nowhere, Gonzalez was equitably estopped to oppose arbitration as to them even though they were not parties to the employment contract or its arbitration clause.  The decision disagrees with and refuses to follow Jarboe v. Hanlees Auto Group (2020) 53 Cal.App.5th 539.
