What Is Workday?
Workday creates software that helps companies hire employees. Its platform uses artificial intelligence to screen job applications. Over 10,000 organizations around the world use Workday’s services.
The company reviews millions of job applications every year. In May 2023 alone, Workday processed 2.2 million U.S. job applications, which was almost 22% of all job openings that month.
The Workday Discrimination Lawsuit Explained
Several job seekers filed a workday class action lawsuit in federal court. They claim Workday’s AI system rejects qualified applicants unfairly. The lawsuit focuses on discrimination based on age, race, gender, and disability.
The plaintiffs say Workday’s automated screening tools have built-in bias. These tools use algorithms to decide who gets hired. The lawsuit argues these algorithms discriminate against protected groups.
Mobley v. Workday, Inc.
Current Status
Key Legal Issues
- Whether algorithmic screening systems constitute unlawful employment practices under the ADEA
- Workday’s potential liability as both software provider and employer intermediary
- Standards for collective and class certification in algorithmic discrimination cases
Who Are the Plaintiffs?
Derek Mobley leads the case. He is an African American man over 40. Mobley graduated from Morehouse College with honors. He has extensive work experience in finance and technology.
Mobley applied for more than 100 jobs through Workday’s platform but was rejected every time. Many rejections came within hours, sometimes even at unusual times like 2 a.m.
Three other plaintiffs joined the case:
- Jill E. Hughes, a female cancer survivor over 40
- Sheilah Johnson-Rocha, an African American woman over 40
- Faithlinh Rowe, an Asian American woman over 40
How Workday AI Works
Workday uses artificial intelligence and machine learning to automatically screen job applications. The system looks at keywords, skills, and work history.
The workday AI platform makes recommendations to employers. It decides which candidates move forward. It also determines which applications get rejected.
In 2024, Workday bought a company called HiredScore. This added more AI features to its platform. This integration took place before many of the lawsuit’s claims.
What the Lawsuit Claims
The workday lawsuit AI makes several serious allegations:
Age Discrimination
The lawsuit says Workday’s system discriminates against workers over 40. This violates the Age Discrimination in Employment Act. Statistical analysis shows big differences in rejection rates.
The data reveals rejection rates more than three standard deviations from normal. This suggests the system treats older applicants differently.
Race Discrimination
The complaint says African American applicants are treated unfairly. Workday’s own audit data supports this, showing a disparity of more than 15 standard deviations from what’s expected.
These numbers suggest the discrimination is very unlikely to be random. The odds are greater than one in a quadrillion.
Standard deviation measures how unusual a result is. Think of it like this: if you flip a coin 100 times, you expect about 50 heads. Getting 52 heads is normal. Getting 90 heads means something is wrong with the coin.
In statistics, 2 standard deviations means there’s only a 5% chance the result happened by accident. At 3 standard deviations, there’s less than 1% chance it’s random. Workday’s results show 15 to 36 standard deviations. This is like flipping a coin and getting heads 10,000 times in a row. It proves the system is biased.
Gender Discrimination
Female applicants also have higher rejection rates. The audit data shows differences of more than 36 standard deviations, affecting women of all ages and races.
Disability Discrimination
The lawsuit questions Workday’s use of personality tests, which may reveal mental health conditions. The plaintiffs argue this breaks disability discrimination laws.
The Evidence
Plaintiffs submitted detailed records of their application experiences. Hughes applied for hundreds of positions. She received automated rejections even though she met all qualifications.
Johnson-Rocha submitted approximately 2,000 applications. Nearly all resulted in automated rejections. Many jobs remained unfilled and were reposted repeatedly.
Rowe applied for an HR Technology position at AT&T. She received an immediate rejection. The rejection came despite her extensive HR experience.
How AI Can Discriminate
The lawsuit explains how algorithmic bias works. AI systems learn from historical data. If that data contains bias, the AI reproduces it.
Amazon famously stopped using a hiring algorithm in 2017 because it favored male candidates over equally qualified women. The system learned this bias from past hiring patterns.
Workday’s system may have similar issues. The algorithms might use indirect clues for protected characteristics. For example, the college someone attended could be linked to race.
Workday’s Role as an Employer Agent
The lawsuit says Workday acts as an employment agent because companies let its platform make hiring decisions. This, they argue, makes Workday responsible for any discrimination.
Job seekers can’t avoid Workday’s system. To apply for jobs at companies that use Workday, they have to use the platform. This gives Workday control over who gets considered for jobs.

Company Response: How Workday Answered the Allegations
Workday officially responded to the lawsuit in August 2024, strongly denying all discrimination claims. Their response outlines their defense strategy.
Workday Denies Being an Employer
Workday’s main defense challenges the lawsuit’s basic claim. The company says it is not an employment agency or an indirect employer.
Workday argues that it only provides software to companies, and that employers make their own hiring decisions. Workday says it does not screen or reject applicants.
Denying Discriminatory Products
Workday denies that its products cause discrimination. The company says its tools do not make hiring decisions and that employers control how they use the software.
Workday also says it does not offer or run personality tests. The company denies doing assessments that reveal disabilities and rejects claims about illegal disability questions.
Key Points from Workday’s Defense
The company’s answer includes several important denials:
- Workday denies delegating hiring authority from employers
- The company denies screening prospective employees for customers
- Workday denies its AI tools make employment decisions
- The company denies any products reinforce discrimination
Workday’s Affirmative Defenses
Besides denying the allegations, Workday raised several legal defenses. These could end the lawsuit even if some claims are found true.
The company argues that the lawsuit does not state valid legal claims. Workday also says some claims may be too old and questions if a class action is the right approach.
Workday says it always acted in good faith and had reasonable reasons for its actions. The company denies any bad intent or reckless behavior.
What Workday Admits
The company did admit some basic facts. Workday confirms it provides human resource management services and serves medium and large organizations in many industries.
Workday admits it processed 2.2 million job applications in May 2023, which was 22% of all U.S. job openings that month. The company also confirms that customers buy subscriptions to its services.
Workday also admits that some of its tools use AI and machine learning, but says these tools do not make hiring decisions.
Major Case Developments
The workday discrimination lawsuit has progressed significantly since it was filed. Several important events have shaped the case.
Federal Court Grants Conditional Certification
On May 16, 2025, Judge Rita F. Lin granted preliminary collective certification. This was a major victory for the plaintiffs. It allows other affected workers to join the lawsuit.
The court authorized a notice plan to reach potential class members. Workers over 40 who applied through Workday can now opt in. The notice process began in late 2025.
Growing Number of Plaintiffs
The case started with one plaintiff in February 2023. Now, over 200 workers have joined the lawsuit. They filed consent forms to become part of the collective action.
New plaintiffs continue joining regularly. Court records show consent forms filed throughout 2025 and into 2026. Each new plaintiff strengthens the case against Workday.

EEOC and AARP Support the Case
The U.S. Equal Employment Opportunity Commission filed an amicus brief. The EEOC supports the plaintiffs’ position. This federal agency enforces employment discrimination laws.
The AARP Foundation also filed to support the plaintiffs. AARP advocates for workers over 50. Their involvement highlights age discrimination concerns.
These organizations bring expertise and credibility to the case. Their support suggests the lawsuit raises important legal issues.
Second Amended Complaint Filed
On January 7, 2026, plaintiffs filed a Second Amended Complaint. This updated version includes three additional named plaintiffs. It also contains new allegations based on discovery.
The amended complaint adds claims about Workday’s acquisition of HiredScore. This AI company was integrated into Workday’s platform. The plaintiffs argue this made discrimination worse.
Court Battles Over Discovery
The parties have fought extensively over document production. Plaintiffs want access to Workday’s AI algorithms and bias testing data. Workday has resisted providing some information.
Multiple discovery disputes have reached the court. Judge Laurel Beeler handles these discovery matters. The fights continue as the case progresses.
Motion to Dismiss Partially Granted in Workday Lawsuit
On March 6, 2026, Judge Lin ruled on Workday’s motion to dismiss. The court granted the motion in part and denied it in part. Some claims were dismissed, but key allegations survived.
The court allowed plaintiffs to file a Third Amended Complaint. This gives them another chance to strengthen their case. The deadline is March 27, 2026.
The Court’s Previous Rulings
Workday’s answer references earlier court decisions. The court previously dismissed some of the plaintiff’s claims. This included intentional discrimination claims under certain laws.
The court also dismissed claims that Workday aided and abetted discrimination. However, disparate impact claims remain active in the case.
These dismissals help Workday’s case, but the main discrimination claims are still moving forward.
Federal Court Authorization
A federal court recently allowed notice in this case, which means the lawsuit can move forward and more workers can join the class action against Workday.
The court recognized the potential merit of the claims. This is an important step in the legal process.

Business Implications
Beyond financial costs, Workday faces other risks. The lawsuit challenges the core of their business model. If the AI system is found discriminatory, major changes would be required.
Workday might need to redesign its entire platform. This could be expensive and time-consuming. It might also reduce the system’s efficiency.
Other companies using AI for hiring are watching closely. The case could set standards for the entire industry. A ruling against Workday could affect many businesses.
What The Workday AI Lawsuit Means for Job Seekers
This case brings up important questions about using AI in hiring. Automated systems can continue discrimination, and job seekers deserve fair treatment no matter their age, race, or gender.
The lawsuit seeks several remedies:
- Stop Workday from using discriminatory algorithms
- Compensate affected job seekers for lost opportunities
- Require changes to Workday’s screening processes
- Establish safeguards against future discrimination
Potential Outcomes
If the plaintiffs win, the impact could be significant. Workday might pay substantial damages to class members. The company would likely need to change its AI systems.
The case could also result in industry-wide changes. Other companies might voluntarily review their AI hiring tools. New regulations could emerge to prevent algorithmic discrimination.
Even if Workday prevails, the case raises awareness. Employers and technology companies now understand the risks. This could lead to more careful AI development and deployment.
The Workday Lawsuit Bigger Picture
This workday discrimination lawsuit raises questions about AI ethics. As more companies use automated hiring tools, fairness is more important than ever. Technology should help people, not hurt them.
The case could set important legal standards for AI hiring systems. Other companies using similar technology are watching closely.
Regulatory Attention
Government agencies are paying attention to AI discrimination. The EEOC has issued guidance on algorithmic hiring tools. States like California and New York have passed new laws.
These regulations require transparency and testing. Companies must ensure their AI systems don’t discriminate. Violations can result in penalties and lawsuits.
The Workday case could influence future regulations. Courts and lawmakers will watch the outcome. It may shape how AI hiring tools are governed.
