Background
Kenneth Doss worked as a yard hostler at Tesla’s Fremont manufacturing facility from 2017 to 2021. His job was to drive tractor trucks to move and position 53-foot trailers — filled with auto parts shipped from out of state — within the factory’s truck yard so the trailers could be docked and their contents unloaded for use in vehicle assembly. Doss never crossed state lines; he moved trailers from one part of the factory grounds to another.
Doss filed a putative class action against Tesla for wage and hour violations under California law. Tesla moved to compel individual arbitration under the Federal Arbitration Act (FAA), relying on an arbitration agreement that also contained a class action waiver. The dispute turned on a critical threshold question: did the FAA’s labor exemption apply to yard hostlers?
The FAA governs arbitration in contracts involving interstate commerce, but it expressly exempts from coverage the employment contracts of “seamen, railroad employees, or any other class of workers engaged in foreign or interstate commerce.” (9 U.S.C. § 1.) The United States Supreme Court has interpreted this “section 1 exemption” to cover “transportation workers” who play a necessary role in the flow of interstate commerce. The question before the court was whether a worker who never leaves factory grounds — but whose job is to move trailers that have just arrived from out of state — qualifies.
The Court’s Holding
The First District, Division Three affirmed the trial court’s denial of Tesla’s motion to compel arbitration on the section 1 exemption question, and its published holding makes yard hostlers exempt from the FAA.
The court analyzed the issue through the framework established by recent Supreme Court decisions, particularly Southwest Airlines v. Saxon (2022) and Flowers Foods, Inc. v. Brock (2026). The key inquiry is whether the workers perform activities “within the flow of interstate commerce” — and workers need not cross state lines or be employed by a transportation company to qualify. Yard hostlers move the very same 53-foot trailers that traveled interstate, positioning them so their contents can be unloaded and received. That work is not incidental to the interstate transaction; it is a necessary step in completing it. The fact that the goods were ultimately bound for incorporation into Tesla vehicles (rather than re-shipment) did not sever the connection to interstate commerce, because the trailers had not yet been unloaded when the hostlers performed their work.
On California law: the published opinion also addressed Labor Code § 229, which allows courts to disregard arbitration agreements for “actions to enforce the provisions of this article for the collection of due and unpaid wages.” The court held that this provision applies to Doss’s claims for failure to pay minimum/regular wages (Count 1) and failure to pay all wages upon termination (Count 6), but not to overtime claims, meal and rest break premium claims, or wage statement claims — because those claims are about failures to provide breaks or furnish records, not about the nonpayment of wages as such. The court disagreed with a 2014 decision (Lane) to the extent it excluded wage-termination claims from § 229’s coverage, aligning instead with the Supreme Court’s analysis in Naranjo v. Spectrum Security (2022).
Key Takeaways
- Tesla’s yard hostlers who move interstate-commerce trailers within factory grounds are “transportation workers engaged in interstate commerce” exempt from the FAA under 9 U.S.C. § 1, meaning their arbitration agreements are governed by California law, not federal arbitration law.
- The section 1 exemption can apply to purely intrastate, even intrafactory, work if the worker handles instrumentalities of interstate commerce (like trailers hauled across state lines) as a necessary step in completing an interstate delivery.
- Labor Code § 229 allows courts to override arbitration agreements for claims seeking unpaid minimum wages and unpaid wages upon termination, but not for overtime claims, meal/rest break premium claims, or wage statement claims — those are categorized as claims about employer conduct, not nonpayment of wages.
- The Gentry factors for invalidating class action waivers in wage cases survived FAA preemption here because the FAA doesn’t apply — California courts can continue to apply the Gentry test when state arbitration law governs.
- Employers in industries where goods arrive by interstate truck should assess carefully whether their warehouse, receiving, or logistics employees fall within the section 1 transportation worker exemption before relying on FAA-based arbitration agreements.
Why It Matters
The section 1 transportation worker exemption has become one of the most litigated issues in California employment arbitration. This decision pushes the exemption further into the factory floor: even workers who never set foot outside a plant’s gates can qualify if the goods they handle arrived from out of state and are still in the process of being received. For manufacturers, warehouse operators, and logistics companies across California, the practical impact is significant — employees performing receiving and unloading functions may be governed by California arbitration law (and therefore subject to California’s class-action and wage-and-hour protections) rather than the FAA.
The Labor Code § 229 analysis is equally useful for practitioners. The court drew careful lines between claims that seek wages (which § 229 can protect from arbitration) and claims that seek compensation for an employer’s failure to provide breaks or accurate pay records (which § 229 cannot). These distinctions matter both at the pleading stage and when evaluating the scope of arbitration agreements in wage-and-hour cases.
