A landmark lawsuit against Workday‘s algorithm-based hiring technology could redefine the legal boundaries for AI in employment screening. The case, which a California judge has allowed to proceed as a collective action, represents a critical test of whether automated screening tools violate anti-discrimination laws when they potentially disadvantage protected groups. As companies increasingly adopt AI for hiring decisions, this precedent-setting litigation highlights the tension between technological efficiency and workplace fairness.

The big picture: A California judge has green-lit a collective action lawsuit against HR software company Workday, alleging its algorithm-based applicant screening technology discriminates against older job seekers.

  • The plaintiffs, all over 40 years old, claim they were systematically rejected from hundreds of jobs through Workday’s platform, sometimes within minutes of applying.
  • The lawsuit alleges Workday’s algorithms “disproportionately disqualify individuals over the age of forty” when screening and ranking job applicants.

Why this matters: The case could establish legal precedent for how companies can use algorithms and AI in hiring decisions as automation becomes increasingly common in recruitment.

  • Workday’s platform is used by over 11,000 organizations worldwide, giving its hiring algorithms significant influence over labor market access.
  • The outcome may shape future regulations around algorithmic transparency and accountability in employment contexts.

Key details: The lawsuit originated with Derek Mobley, who claims Workday’s algorithms caused him to be rejected from more than 100 jobs over seven years based on his age, race, and disabilities.

  • Four additional plaintiffs have since joined the case, specifically alleging age discrimination.
  • The lawsuit seeks unspecified monetary damages and a court order requiring Workday to change its practices.

What they’re saying: Workday has denied allegations that its technology discriminates, characterizing the judge’s decision as a “preliminary, procedural ruling” that “relies on allegations, not evidence.”

The broader context: AI hiring tools face mounting scrutiny from civil rights organizations concerned about algorithmic bias perpetuating workplace discrimination.

  • The American Civil Liberties Union has warned that AI hiring tools “pose an enormous danger of exacerbating existing discrimination in the workplace.”
  • In 2018, Amazon abandoned an automated candidate ranking system after discovering it favored male applicants over women, highlighting how AI can inadvertently learn and amplify existing biases.

Between the lines: Workday markets its “HiredScore AI” as using “responsible AI” to grade top candidates and reduce application screening time, highlighting the tension between efficiency claims and potential discriminatory impacts.

DOE fusion roadmap targets 2030s commercial deployment as AI drives $9B investment

The Department of Energy has released a new roadmap targeting commercial-scale fusion power deployment by the mid-2030s, though the plan lacks specific funding commitments and relies on scientific breakthroughs that have eluded researchers for decades. The strategy emphasizes public-private partnerships and positions AI as both a research tool and motivation for developing fusion energy to meet data centers' growing electricity demands. The big picture: The DOE's roadmap aims to "deliver the public infrastructure that supports the fusion private sector scale up in the 2030s," but acknowledges it cannot commit to specific funding levels and remains subject to Congressional appropriations.
