As of July 13, 2026, the opt-in window for the Workday age-discrimination collective closed on March 7, 2026, so it is generally no longer possible to join that specific collective. The case itself remains very much alive. On June 22, 2026, U.S. District Judge Rita F. Lin largely upheld claims brought under California’s Fair Employment and Housing Act and the Americans with Disabilities Act, including a disability claim tied to proxy indicators like employment gaps, while dismissing some race-based claims on procedural grounds. A May 29, 2026 discovery order also required Workday to turn over EEO-1 and federal contractor compliance data, while ruling that its internal AI bias-testing data stays protected as privileged. The case now heads toward further discovery and a possible fight over class decertification.
Last updated: July 2026
The Workday lawsuit is one of the biggest employment discrimination cases in American history, and millions of job seekers may have a legal right to join it right now. If you applied for a job through Workday’s platform after September 24, 2020, and you were 40 or older at the time, you could be part of a nationwide collective action that could include hundreds of millions of people.
The case, formally known as Mobley v. Workday, Inc., accuses the HR software company of using AI tools that systematically discriminate against job applicants based on their age, race, and disability status. The court certified the case as a collective action in May 2025.
There is a critical deadline. To participate, affected job seekers must submit an Opt-In Consent to Join form by March 7, 2026. Miss that date, and you lose your right to any financial recovery from this specific case.
This article covers who qualifies, what the AI tools actually did, how the legal case unfolded, and exactly what steps you need to take before the window closes.
What Is the Workday Lawsuit?
The Workday lawsuit is a federal collective action alleging that Workday’s AI-powered hiring software discriminated against job applicants based on age, race, and disability.
The case, Mobley v. Workday, Inc. (Case No. 23-cv-00770-RFL), is being heard in the Northern District of California. It targets Workday’s applicant recommendation systems, which are used by thousands of companies to sort and screen job applications.
Workday is not a small player. Over 11,000 organizations worldwide use Workday’s services. That scale is exactly why this lawsuit matters so much.
Think of it like a broken filter on a massive water pipe. Millions of applications flowed through that filter, and the allegation is that the filter was rigged from the start.
| Case Detail | Information |
|---|---|
| Case Name | Mobley v. Workday, Inc. |
| Case Number | 3:23-cv-00770-RFL |
| Court | U.S. District Court, Northern District of California |
| Judge | Rita F. Lin |
| Filed | February 21, 2023 |
| Class Period | September 24, 2020 to present |
| Opt-In Deadline | March 7, 2026 |
What Is the Workday Class Action Lawsuit About?
The Workday class action lawsuit claims that the company’s AI hiring tools created a discriminatory screening system that filtered out older, non-white, and disabled job applicants before any human reviewer ever saw their resumes.
The lawsuit claims that Workday’s AI-driven hiring system plays a direct role in rejecting or recommending candidates, and that the software may use proxy indicators such as schools attended that correlate with race, age, or disability.
The result, plaintiffs argue, is a system that replicates human bias at digital speed. The disparate impact framework under Title VII and the ADEA allows plaintiffs to challenge facially neutral employment practices that disproportionately harm protected groups.
The lawsuit does not claim that any Workday executive sat down and said, “Let’s discriminate.” It claims the discrimination was baked into the system’s design and training data.
- The lawsuit alleges violations of the Age Discrimination in Employment Act (ADEA)
- It also includes claims under Title VII of the Civil Rights Act of 1964
- Americans with Disabilities Act (ADA) claims are part of the case as well
Key Takeaway: The Workday class action lawsuit is not about individual bias. It is about a software system that allegedly filtered out millions of applicants based on protected traits automatically.
Workday Lawsuit: How to Join Before the Deadline
To join the Workday lawsuit, you must submit an Opt-In Consent to Join form by March 7, 2026.
To join this case, you must complete, sign, and return the Opt-In Consent to Join Form. The form requires that you sign page one and list your contact information and your birthday on page two.
This is not a standard class action where you are automatically included. This is a collective action, which means you are not part of the lawsuit unless you proactively sign a “Consent to Join” form. If you ignore the mailer or email and the deadline of March 7, 2026 passes, you lose your right to any financial recovery from this specific case.
Here is how to join:
- Visit the official case website at workdaycase.com (no link; search the name directly)
- Complete the electronic Opt-In Consent to Join form
- Confirm you applied through Workday’s platform while aged 40 or older after September 24, 2020
- Submit before March 7, 2026
You will not be responsible for paying any lawyers’ fees. Plaintiffs’ attorneys are being paid on contingency, which means that if plaintiffs do not receive a recovery in this case, no lawyer fees will be owed.
Workday Lawsuit Eligibility Requirements
You qualify for the Workday lawsuit if you meet three conditions: age, date range, and outcome.
The certified collective includes all individuals aged 40 and over who, from September 24, 2020, through the present, applied for job opportunities using Workday’s job application platform and were denied employment recommendations.
You don’t need to prove you were the best candidate. You don’t need to show that a human intentionally discriminated against you. The claim is about the system, not one specific person’s choice.
| Eligibility Requirement | Details |
|---|---|
| Minimum Age | 40 years old at time of application |
| Application Date | On or after September 24, 2020 |
| Platform Used | Workday’s job application platform |
| Outcome Required | Denied an employment recommendation by the AI system |
| Race Requirement | None specified for ADEA claim |
| Disability Requirement | None required for ADEA claim |
| Cost to Join | Zero; attorneys work on contingency |
If you’re unsure whether the company you applied to used Workday, look back at your application confirmation emails. Many companies that use Workday send rejections from a Workday-branded portal.
Workday Lawsuit Opt-In Deadline 2026: What You Need to Know Now
March 7, 2026 is the opt-in deadline for the Workday lawsuit, and it is not negotiable.
As of January 30, 2026, a nationwide collective action lawsuit against Workday, Inc. is moving forward in a California federal court. The court approved a formal notice plan in December 2025, meaning official notices have been going out to potential class members.
If you receive a mailer or an email about the Workday lawsuit, it is not spam. It is an official court notice.
Missing this deadline has real consequences:
- You lose your right to participate in any financial recovery from this case
- You cannot join the collective action after the deadline closes
- You may still have separate legal options, but those require filing your own lawsuit
The court authorized notices to go out through mail, email, and potentially social media platforms. The judge ordered Workday to provide a list of customers using their AI screening features so applicants can be notified and given the opportunity to opt in.
Key Takeaway: March 7, 2026 is a hard stop. If you think you qualify, submit your opt-in form now, not later.
What Is the Workday AI Discrimination Lawsuit Specifically Claiming?
The Workday AI discrimination lawsuit is specifically claiming that Workday’s algorithm created a disparate impact on applicants over 40, on Black applicants, and on applicants with disabilities, even without any intentional discrimination.
Disparate impact is a legal theory that says a policy can be illegal even if it was not designed to discriminate. The key question is: did the policy hurt a protected group more than others?
The plaintiffs argue that Workday’s algorithm functionally deprioritized older applicants, effectively excluding a protected class from employment consideration. According to the complaint, the discrimination flowed from the software’s design, ranking, screening, and filtering in ways that penalized age with no human intervention.
The EEOC agreed that the theory had merit. In April 2024, the EEOC supported the plaintiff by submitting a legal brief stating that algorithmic hiring tools like those used by Workday can violate anti-discrimination laws, even without explicit intent.
The government’s support of this legal theory was a significant moment. It signaled that federal regulators believe AI tools can discriminate, full stop.
Mobley v. Workday: The Case That Started It All
Mobley v. Workday began with one man’s experience applying for over 100 jobs and getting rejected from every single one, often within minutes.
Derek Mobley, a seasoned professional with a degree from Morehouse College and experience across finance, IT, and customer service, submitted more than 100 job applications through Workday’s platform. He was rejected every time, often within minutes, sometimes in the middle of the night, without an interview.
The court cited allegations that the plaintiff was rejected at the screening stage from over 100 positions of a wide range and type, even though he was allegedly qualified for all of those jobs, as well as rejection emails received outside of business hours and within an hour after submitting applications.
Mobley is a Black man over 40 who also identifies as having anxiety and depression. His complaint specifically called out discrimination based on all three of those protected characteristics.
He says he applied to more than 100 jobs with companies that use Workday’s AI-based hiring tools over the course of several years and says he was rejected every single time.
Four additional plaintiffs with similar experiences joined the case. Their stories were nearly identical: dozens or hundreds of applications, near-instant rejections, and zero interviews.
Workday Age Discrimination Lawsuit: Who Is Affected
The Workday age discrimination lawsuit targets applicants who were 40 or older when they applied through Workday’s platform after September 24, 2020.
The Northern District of California conditionally certified Age Discrimination in Employment Act (ADEA) claims on behalf of a collective believed to include millions of job applicants.
Workday represented in its court filings that 1.1 billion applications were rejected using its software tools during the relevant period, so the collective action could potentially include hundreds of millions of rejected applicants.
That number is hard to wrap your head around. One billion applications. Even if a small fraction of those involved people over 40, the class size is enormous.
The ADEA is the federal law that makes it illegal to discriminate against workers and applicants aged 40 and older. The lawsuit claims Workday’s AI violated this law by systematically downgrading older applicants’ recommendations.
| Age Discrimination Claim Detail | Information |
|---|---|
| Law at Issue | Age Discrimination in Employment Act (ADEA) |
| Protected Age Group | 40 years old and older |
| Class Period Start | September 24, 2020 |
| Total Applications Rejected | 1.1 billion (per Workday’s own filings) |
| Certification Date | May 16, 2025 |
| Certifying Judge | Rita F. Lin |
Key Takeaway: The age discrimination claim covers anyone 40 or older who used Workday’s platform since late September 2020 and was rejected by its AI system.
Workday Race Discrimination Lawsuit: What the Claims Say
The Workday race discrimination claims allege that the AI tools produced outcomes that disproportionately hurt non-white applicants, particularly Black job seekers.
Lead plaintiff Derek Mobley is Black. His complaint specifically included race discrimination claims under Title VII of the Civil Rights Act and under Section 1981.
The lawsuit alleges the AI inadvertently penalizes older, non-white, or disabled applicants, effectively replicating human bias in a digital format.
The theory is that the AI was trained on data from existing workforces. If those workforces were predominantly white and younger, the AI would have learned to favor resumes that “look like” those employees. That creates racial bias without anyone typing a discriminatory command.
The race discrimination claims under Title VII and Section 1981 were partially narrowed during early court proceedings. The court granted the defendant’s motion to dismiss in part, dismissing the intentional discrimination claims under Title VII, the ADEA, and Section 1981.
The surviving claims focus on the disparate impact theory, not intentional discrimination.
Workday Disability Discrimination Lawsuit: What Applicants Alleged
The Workday disability discrimination claims allege that the AI screening tools also systematically disadvantaged applicants with disabilities.
Derek Mobley disclosed that he has anxiety and depression. His original complaint included ADA claims based on the idea that the AI could identify and deprioritize applicants whose resumes or application patterns reflected disability-related characteristics.
The lawsuit claims that Workday’s AI models were trained on data from incumbent employees, which often reflects a less diverse workforce. This means the algorithm may have learned to favor younger candidates or those with specific resume formats that older or disabled workers don’t typically use.
Like the race discrimination claims, the ADA claims also went through multiple rounds of court motions. The intentional discrimination angle was dismissed. The disparate impact theory survived.
Applicants with disabilities who used Workday’s platform since September 24, 2020 should review their eligibility carefully, particularly if they are also 40 or older.
How Workday’s Hiring Algorithm Discrimination Works
Workday’s hiring algorithm discrimination allegedly worked by using biased training data to score, rank, and filter applicants before any human saw their credentials.
Workday has AI-based applicant screening tools. Candidate Skills Match extracts skills in the employer’s job posting and the applicant’s materials and determines the extent to which the applicant’s skills match the role. The results are reported to the employer as “strong,” “good,” “fair,” “low,” “pending,” and “unable to score.”
The second tool is more concerning. The Workday Assessment Connector allegedly uses machine learning to observe that an employer disfavors certain candidates who are members of a protected class and decreases the rate at which it recommends those candidates.
In plain English: the AI watched which candidates employers rejected, learned their patterns, and started pre-rejecting similar applicants automatically.
If an employer historically passed over older applicants, the AI learned to do the same thing faster. It’s like teaching an intern by showing them only the bad examples.
- Candidate Skills Match: Scores and ranks applicants against job descriptions
- Assessment Connector: Learns employer preferences and applies them algorithmically
- HiredScore: A separate AI tool acquired by Workday, now also included in the lawsuit
Key Takeaway: The discrimination allegedly happened at the algorithm level, not the human decision level. The AI was screening people out before any hiring manager could ever say yes.
The Workday AI Bias Lawsuit: Why Courts Took It Seriously
Courts took the Workday AI bias lawsuit seriously because the evidence was hard to explain away.
The court cited the sheer number of rejections and the timing of those decisions, coupled with allegations that Workday’s AI systems rely on biased training data, as support for a plausible inference that Workday’s screening algorithms were automatically rejecting applications based on a factor other than qualifications, such as a protected trait.
Getting rejected in the middle of the night within an hour of applying is not how human hiring works. Those patterns pointed directly to automated decision-making.
The EEOC’s decision to file an amicus brief also carried weight. The EEOC filed an amicus brief supporting the novel theory of liability and urging the Court to deny the motion to dismiss.
The Court’s July 12, 2024 decision emphasized the importance of the agency theory in addressing potential enforcement gaps in anti-discrimination laws, illustrating potential gaps with a hypothetical scenario where a software vendor intentionally creates a tool that screens out applicants from historically Black colleges and universities, unbeknownst to the employers using the software.
When a federal agency, a federal judge, and multiple rounds of litigation all conclude that a theory of AI discrimination is legally plausible, that matters.
The Workday HiredScore Lawsuit: What That Means for You
The Workday HiredScore lawsuit refers to the expansion of the collective action to include applicants screened using Workday’s HiredScore AI features, which Workday acquired after the original lawsuit was filed.
Workday Inc. must provide a list of customers who enabled HiredScore artificial intelligence features in their hiring process, even though the company acquired the technology after the original complaint was filed, a judge in the U.S. District Court for the Northern District of California ruled.
Workday tried to exclude HiredScore from the lawsuit. The court rejected that argument. The court further held that the preliminary collective included applicants whose applications were scored, ranked, or screened using Workday’s HiredScore AI features. It rejected Workday’s arguments that HiredScore was acquired later, was a separate product, or used different algorithms.
This matters for potential class members. If you applied to a company that used HiredScore after the tool was integrated into Workday’s systems, your application may still be covered.
The court ordered Workday to identify every customer that had enabled HiredScore features and to include those applicants in the notice process.
Key Takeaway: HiredScore is now part of the lawsuit. If you applied through any Workday-powered portal, your application may have been screened by HiredScore even if you never heard of it.
Workday Lawsuit Settlement Amount: What to Expect
There is no confirmed Workday lawsuit settlement amount yet because the case has not reached a settlement or final judgment.
This is important to understand. The case is still in active litigation. No settlement has been announced. No checks are being sent out.
Because this is currently a collective action and not yet a finalized settlement, there is no fixed payout amount yet. In successful employment discrimination lawsuits, relief typically includes back pay, compensatory damages for emotional distress, and injunctive relief requiring the defendant to change its practices.
Here is what prior employment discrimination class actions suggest about potential outcomes:
| Damage Type | What It Covers |
|---|---|
| Back Pay | Wages lost because of discriminatory rejections |
| Front Pay | Future lost earnings in some cases |
| Compensatory Damages | Emotional distress, job search costs |
| Injunctive Relief | Court order requiring Workday to change its AI |
| Attorneys’ Fees | Paid from any recovery; no cost to plaintiffs |
The size of any individual payout would depend on the number of class members who opt in, the total recovery, and how the settlement or judgment is structured. With potentially hundreds of millions of class members, individual payments could vary widely.
Workday AI Lawsuit 2026 Update: Where Things Stand Right Now
The Workday AI lawsuit is currently in the collective action notification phase as of early 2026, with active court proceedings continuing alongside the opt-in process.
The court approved a plan for providing notice to prospective members of the collective on December 2, 2025. That means official court notices went out starting in late 2025.
Recent Update (January 21, 2026): Workday filed a motion to dismiss a specific portion of the claims, arguing that the Age Discrimination in Employment Act does not allow disparate impact claims for job applicants. However, as of January 30, 2026, the court’s authorization for the nationwide collective remains active.
Workday is still fighting. That is expected. Defendants in class actions routinely file motions to narrow or dismiss claims throughout the litigation. The court’s refusal to shut down the collective action entirely is the key signal to watch.
The next major procedural step after the opt-in period closes will be further discovery, followed by Workday’s potential motion to decertify the class.
- December 2, 2025: Court approves notice plan for collective members
- March 7, 2026: Opt-in deadline for all potential class members
- Ongoing: Workday continues to fight portions of the claims
- Future: Decertification proceedings possible after discovery
Key Takeaway: The case is active and moving forward. The court has not wavered on the core collective action certification. Your window to join closes March 7, 2026.
