Workday Lawsuit: Mobley v. Workday Explained for Job Applicants

TL;DR: The Workday lawsuit, Mobley v. Workday, claims that AI features in Workday's hiring software screen out applicants who are 40 or older, Black, female or disabled. The window to join the age-discrimination collective closed on 7 March 2026 (late forms were accepted until 14 April 2026). Nothing has been decided on the merits. A class certification motion that could cover more applicants is pending, with a hearing noticed for 9 March 2027. If you apply through Workday now, keep a record of each application.

What is the Workday lawsuit about?

Mobley v. Workday, Inc.: a federal case in the Northern District of California (No. 3:23-cv-00770-RFL, Judge Rita F. Lin), filed on 21 February 2023, alleging that Workday's AI applicant-screening tools have a disparate impact on job applicants because of age, race and disability, and later sex.

Derek Mobley describes himself as a Black man over 40 with anxiety and depression, as the January 2024 order summarizes his complaint. According to the preliminary certification order, he alleges that since 2017 he has applied to more than 100 jobs at employers that use Workday and was rejected for every one. The case is unusual because he did not sue those employers. He sued the software vendor.

The legal question at the center of the case is whether a vendor can be liable at all. Workday argued that, as a software company, it is not an employer. On 12 July 2024 the court disagreed at the pleading stage: Title VII, the ADEA and the ADA define "employer" to include "any agent" of an employer, and Workday plausibly acted as one because its tools allegedly "perform a traditional hiring function of rejecting candidates at the screening stage and recommending who to advance." The order adds that a spreadsheet or email provider would not qualify, because those tools take no part in deciding whom to hire.

Three Workday features are named in the record:

• Candidate Skills Match (CSM), inside Workday Recruiting. In discovery Workday described it as AI that extracts skills from the job posting and from your application or resume, then reports the match as "strong," "good," "fair," "low," "pending" or "unable to score" (quoted in the May 2025 order).
• HiredScore Spotlight, which Workday acquired after the suit was filed. Workday's own documentation grades candidates A to D on how well the resume matches the basic and preferred qualifications in the job description.
• HiredScore Fetch, which the plaintiffs' class certification motion says "searches for, screens, and recommends" candidates, including people who had not applied. That description is the plaintiffs' allegation.

Workday denies the core claim. Its interrogatory answer, quoted in the May 2025 order, says it "does not recommend, screen out, or otherwise assess or predict applicants' likelihood of success in a role," and a Workday declaration says customers can "enable, disable, use, or ignore" the AI features.

Workday lawsuit timeline: what the court has decided

Every row below comes from an order or filing on the court docket, checked on 13 October 2026.

Can you still join the Workday lawsuit?

For the age claim, almost certainly not. An ADEA collective is opt-in: you are part of it only if you file a consent form. The court-approved notice went to "all individuals 40 years of age or older who, at any time from September 24, 2020 to the present, applied for job opportunities using Workday, Inc.'s job application platform," and the notice plan required forms dated no later than 7 March 2026.

More than 500 people sent forms after that date. On 14 April 2026 the court let in everyone who had submitted by that day and set a hard rule for anyone later: you must file an affidavit on the docket explaining why you were late, and the order says further leave will not be granted "absent an individualized good cause showing." The same order told plaintiffs' counsel to take workdaycase.com offline by 15 April 2026 so nobody would think the form was still open. By the 7 October 2026 discovery order, more than 15,000 people had opted in.

The second route is still open in principle, and it needs no action from you today. On 14 September 2026 the plaintiffs moved to certify a Rule 23 class of people subjected to HiredScore Spotlight, Fetch or Candidate Skills Match who were not selected for favorable consideration, with four subclasses: Black applicants, women, applicants with disabilities, and an age subclass under California's Fair Employment and Housing Act. The motion is noticed for a hearing on 9 March 2027.

A Rule 23 damages class works the other way round from the ADEA collective. If a court certifies one under Rule 23(b)(3), members are in by default, and Rule 23(c)(2)(B) requires notice telling them the court "will exclude from the class any member who requests exclusion" and how to do it. So if the class is certified, you would hear about it through court-approved notice. Treat any site that asks for a fee or your Workday login to "join" as a red flag; the court's own notice process is the route.

What the court has not decided

The age collective is easy to over-read, so here is what the record does not say.

Nobody has won. The May 2025 order calls the certification stage "loosely akin to a plausibility standard" and says its "sole consequence" is sending notice. Workday's motion to decertify is due on 10 November 2026; at that stage, the same order explains, the court takes "a more exacting look" at whether the opt-ins are similarly situated. If Workday succeeds, each person would have to proceed individually.

There is no settlement and no payout. No order on the docket approves a settlement, and no damages have been awarded. Pages promising a "Workday lawsuit payout" are describing something that does not exist yet.

Intentional discrimination is out. The July 2024 order dismissed the claims that Workday intended to discriminate, without leave to amend. What remains is disparate impact: the claim that a facially neutral tool produces worse outcomes for a protected group. The May 2025 order expects that question to be argued with statistical evidence across the whole collective.

"Recommendation" is still undefined. The collective covers applicants who were "denied employment recommendations," meaning the AI scored, sorted, ranked or screened the application, the result "was not a recommendation to hire," and it went to the employer or caused an automatic rejection. The court left open whether anything below a "strong" CSM match counts.

The ADEA question may yet go to appeal. The Seventh Circuit held in Kleber v. CareFusion (2019) that applicants cannot bring ADEA disparate-impact claims. Judge Lin has ruled the other way twice, and on 2 July 2026 she refused an early appeal while acknowledging "substantial ground for difference of opinion." The Ninth Circuit can take it up after a final judgment.

What the case means when you apply through Workday

You can usually tell when you are in a Workday application: the careers link moves to a myworkdayjobs.com address, as on Pfizer's and NVIDIA's career sites. That tells you the employer runs Workday Recruiting. It does not tell you whether any AI feature is switched on, because, per Workday's declaration in the record, each customer chooses.

Four points from the record are useful at the application stage.

1. The matchers read skills from your resume. CSM, as Workday described it in discovery, extracts skills from the posting and from your application or resume. HiredScore grades against the basic and preferred qualifications in the job description. Skills written in the posting's own words, in plain text, give both something to match. If you want to see what a parser lifts from your file, run it through the free ATS checker before you apply.
2. Grades are per job. A HiredScore grade measures you against one requisition, so the same resume can be an A for one job and a D for another. Our guide to ATS scores shows what recruiters see for each system.
3. Age can leak through proxies. The May 2025 order noted that graduation year and length of employment experience "will frequently be available to use as a proxy for age." A degree is a qualification; its year usually is not. Leaving graduation dates off older degrees is your choice to make.
4. In New York City you can read the audit. Employers that use an automated employment decision tool on NYC candidates must publish a bias audit summary. Pfizer's audit of HiredScore is one example, covered in our NYC Local Law 144 guide.

No order so far finds any Workday feature biased or requires Workday or its customers to switch one off.

If you think an AI screening tool rejected you unfairly

The case shows what evidence matters. According to the 7 October 2026 order, 38 opt-in plaintiffs gave declarations recounting their job-application history, qualifications and interactions with Workday's platform, and each had already answered eleven interrogatories and nine document requests from Workday.

So keep, for each application: the employer, the job title, the date, the posting text, the resume version you sent, and every automated email with its timestamp. The opt-ins in the May 2025 order each pointed to at least one "automated" rejection for a job whose qualifications they met.

For a claim of your own, the U.S. Equal Employment Opportunity Commission is the starting point. Mobley himself filed an EEOC charge before suing, as the January 2024 order records. The EEOC's time limits page says you generally have 180 calendar days from the discrimination to file a charge, extended to 300 days where a state or local agency enforces a similar law. For age claims, only a state law and state agency extend it; a local law alone does not. The clock starts on the day the discrimination took place, so an old rejection may already be outside it.

Why is Workday being sued?+

Derek Mobley and three other named plaintiffs allege that AI features in Workday's hiring software, including Candidate Skills Match and HiredScore Spotlight and Fetch, have a disparate impact on applicants aged 40 and over, Black applicants, women and applicants with disabilities. Workday denies that its tools recommend or screen out applicants.

How do I join the Workday lawsuit?+

The opt-in for the age collective closed on 7 March 2026, with late forms accepted until 14 April 2026. Anyone later must file an affidavit on the court docket showing individual good cause. A separate class certification motion is pending; if a class is certified, members are included by default and receive court-approved notice.

Does Workday have a class action lawsuit?+

Yes in part. The age claim runs as a preliminarily certified ADEA collective, which people had to opt into. In September 2026 the plaintiffs also asked the court to certify Rule 23 classes for race, sex, disability and California age claims; the court had not ruled on that motion as of 13 October 2026.

What is the current status of the Workday lawsuit?+

As of 13 October 2026 the case is in discovery. Workday's motion to decertify the age collective and its opposition to class certification are due on 10 November 2026, and the class motion is noticed for hearing on 9 March 2027. There has been no ruling on the merits and no settlement.

Is there a Workday lawsuit payout?+

No. The court has not found Workday liable, no damages have been awarded and no settlement has been approved. Any money would come only after a judgment or a court-approved settlement.

Key takeaways

• Mobley v. Workday is about disparate impact: whether Workday's AI matching and grading features produce worse outcomes for older, Black, female or disabled applicants. Claims of intentional discrimination were dismissed in 2024.
• The 2024 agent ruling means a hiring-software vendor can be sued directly when its tool takes part in rejecting or advancing applicants. That holding is at the pleading stage and has not been tested on appeal.
• The age collective closed to new members on 14 April 2026 with more than 15,000 opt-ins. Later joiners need court leave on an individual showing.
• The next moves are Workday's decertification motion and class opposition on 10 November 2026 and a class certification hearing noticed for 9 March 2027. Class membership, if certified, would not require opting in.
• Your own records are the evidence. Save postings, resume versions and timestamped rejection emails; an EEOC charge has to be filed within 180 or 300 days of the discrimination.
