What this is
In Mobley v. Workday, a U.S. federal court allowed claims to proceed that Workday’s AI-powered applicant screening could create employment-discrimination liability — including, in 2025, conditional certification of an age-discrimination collective. The live question for buyers: vendors may be treated as agents, not just software.
A 2025 U.S. court milestone: AI hiring vendors may face collective discrimination claims as “agents,” not only as software.
- Mobley v. Workday: alleged disparate impact in AI applicant screening (age, race, disability).
- July 2024: claims survive dismissal on an agent-liability theory.
- May 2025: conditional ADEA collective certification — a live buyer-risk signal.
- Employment AI remains a regulated selection procedure, whatever the vendor slide says.
Next action: Inventory HR AI that ranks or screens candidates; require counsel review and vendor audit rights before the next renewal.

What changes in how you lead
How decision rights, process, and ownership should change.
- Treat screening tools as selection procedures with documentation and human appeal.
- Ask vendors how they defend agent-liability theories — and put answers in the contract.
- HR, Legal, and Purchasing co-own people-decision AI; IT cannot buy this alone.
Deep dive
Derek Mobley alleged that Workday’s algorithmic screening tools had a disparate impact on applicants by age, race, and disability after he applied to many jobs through the platform.
In July 2024 a Northern District of California court allowed key claims to proceed on an “agent” theory — the vendor might be liable even if it is not the employer. In May 2025 the court conditionally certified ADEA claims for a large applicant collective.
Leadership takeaways: validate on your labor market; require audit rights and human override; do not assume the vendor absorbs employment-law risk.
