Summary

The Mobley v. Workday lawsuit, certified as a nationwide collective action in March 2026, marks the first major U.S. AI hiring discrimination case to reach this stage in U.S. history. Plaintiff Derek Mobley alleges Workday's algorithmic tools repeatedly screened him out based on age, race, and disability, despite Workday's external bias audit, which used NYC Local Law 144 methodology and found no disparate impact. This case highlights that vendor-commissioned audits are not comprehensive legal defenses, as AI tools trained on historical data can perpetuate existing biases at scale. Concurrently, regulatory pressures are intensifying with NYC Local Law 144 already in force and the EU AI Act's high-risk obligations for employment AI taking effect on August 2, 2026. The rise of agentic AI systems, projected for 327% growth by 2027, further complicates oversight, as employers remain legally accountable for AI-driven hiring decisions.

Key takeaway

For CHROs deploying AI-powered ATS, your organization is directly accountable for algorithmic hiring decisions, regardless of vendor audits. The Mobley v. Workday case confirms AI bias risk, and upcoming regulations like the EU AI Act (August 2, 2026) demand robust governance. You must map AI touchpoints, critically assess vendor claims, and ensure human oversight for all consequential outcomes to mitigate significant legal and ethical exposure.
