Mobley v. Workday, Inc.
Where it stands
Judge Rita F. Lin granted PRELIMINARY (conditional) certification of a nationwide ADEA collective under 29 U.S.C. 216(b) on May 16, 2025 — not a Rule 23 class. The long-form notice was approved November 18, 2025 and hundreds of opt-in consents have been filed. A Fourth Amended Complaint adding named plaintiffs was filed July 10, 2026 and answered July 15, 2026. Under the July 13, 2026 schedule, the Rule 23 class-certification motion is due September 14, 2026 and Workday's decertification motion November 10, 2026, with a combined hearing expected in 2027.
Key ruling
May 16, 2025 (N.D. Cal., Lin, J.): conditional certification of a nationwide ADEA collective over an AI applicant-screening tool — the first such collective against an AI hiring vendor.
