California employment case index

The California Supreme Court granted review on March 25, 2026 in Barbosa v. Sierra Pacific Orthopaedic Center Medical Group to decide whether an arbitration agreement that designates the Federal Arbitration Act thereby imports the FAA's substantive provisions and their preemptive force, even where no interstate commerce is shown. The underlying Court of Appeal opinion is nonpublished, and the Court denied the requests to publish it on granting review. The paired grant-and-hold, Tuufuli v. West Coast Dental Administrative Services, is published but itself under review, and answered the question yes. This pending-review analysis sets out the Court's own issue statement, the competing answers below with their correct citability under rule 8.1115(e)(1), and what the answer decides for Armendariz, Labor Code section 432.6, the arbitration-fee statutes and the EFAA.

The Ninth Circuit held the Federal Arbitration Act preempts AB 51 (Labor Code § 432.6), California's attempt to ban mandatory employment arbitration, because a state rule that burdens the formation of arbitration agreements stands as an obstacle to the FAA.

Three Oracle instructors living in Colorado and Arizona worked a limited number of days in California for their California-headquartered employer. Answering certified questions from the Ninth Circuit, the California Supreme Court held that the Labor Code's overtime provisions apply to work performed in this state regardless of residence, and that those violations support a UCL claim – but that the UCL does not reach FLSA violations occurring in other states on these stipulated facts. The court confined its holding to overtime and to entire days and weeks worked in California.
