How to File a Discrimination Lawsuit at Work

Aug 12, 2025

1. Recognizing Workplace Discrimination

Workplace discrimination occurs when an employee is treated unfairly based on protected characteristics such as race, gender, age, religion, disability, or national origin. This can include being denied promotions, receiving lower pay for the same work, or enduring a hostile work environment. Recognizing discrimination is the first step toward taking legal action. It’s important to differentiate between unfair treatment and behavior that violates anti-discrimination laws under the Equal Employment Opportunity Commission (EEOC).

2. Documenting Evidence of Discrimination

Strong evidence is crucial to winning a discrimination case. Keep detailed records of incidents, including dates, times, locations, and the names of witnesses. Save all relevant emails, performance reviews, or other documentation that may demonstrate bias or unfair treatment. The more thorough your evidence, the stronger your claim will be when presented to the EEOC or in court.

3. Reporting to Human Resources or Management

Before filing a lawsuit, most workplaces require you to report discrimination to a supervisor or HR department. This gives the employer an opportunity to address the issue internally. Make sure your complaint is made in writing, and keep a copy for your records. If HR fails to take action or retaliates against you, it can strengthen your case in court.

4. Filing a Complaint with the EEOC

In the U.S., you must file a formal complaint with the EEOC before pursuing a lawsuit. This complaint, known as a “Charge of Discrimination,” must be filed within 180 to 300 days of the incident, depending on your state. The EEOC will investigate, attempt mediation, and may issue you a "Right to Sue" letter if your case qualifies for court. This step is mandatory for most federal discrimination claims.

5. When to File a Lawsuit

Once you receive the “Right to Sue” letter, you can proceed with filing a lawsuit in federal or state court. It’s critical to act quickly because strict deadlines apply. A skilled employment lawyer can help you decide whether to file in federal court for broader protections or in state court for potentially faster resolution.

6. Real-Life Example of a Discrimination Case

Consider a case in Chicago where an employee reported gender-based pay disparities. After months of HR inaction, she filed a complaint with the EEOC, which confirmed a violation. The case moved to court, and the employer settled for back pay, damages, and policy changes. Stories like this demonstrate that pursuing legal action can lead to meaningful change, not just compensation.

7. Working with an Experienced Lawyer

Filing a workplace discrimination lawsuit can be complex, and employers often have strong legal teams. Partnering with experienced attorneys, such as those from ESPLawyers, can help ensure you meet all procedural requirements and present the strongest possible case.
