A federal judge allowed job seekers to pursue a collective action lawsuit against Workday, alleging its AI hiring tools discriminate against older applicants. The case remains a focal point for the over 80% of U.S. employers currently utilizing AI in their recruitment processes.
Why it matters
The litigation challenges the use of software that learns from historical workforce data to screen candidates, potentially perpetuating patterns of past discrimination. As the case proceeds, businesses may face increased scrutiny regarding how their automated hiring systems sort and reject applicants.
Workday, which services two-thirds of the Fortune 500, processed over 356 million job applications and 27 million job offers in 2024. The lawsuit stems from allegations of bias in automated systems, with one lead plaintiff reporting over 100 job applications rejected by the software.

Market Landscape
This lawsuit tests the application of the Age Discrimination in Employment Act to automated algorithmic hiring processes. It marks a critical judicial interpretation of how existing federal anti-discrimination protections apply to modern AI-driven recruitment tools.
Operators currently utilizing AI hiring software should evaluate their vendor audit processes and algorithmic transparency. Compliance teams should review how candidate data is weighted during screening to ensure hiring outcomes do not inadvertently violate protected group criteria.
The takeaway
Businesses must reconcile the efficiency of automated hiring tools with the legal risks posed by algorithmic bias. Ensure that your human resources department conducts regular impact assessments on any automated software that screens or rejects job applicants.
