If you believe your employer treated you worse because of who you are — your race, sex, religion, age, disability, national origin, or another protected trait — you usually cannot go straight to federal court. Federal law routes most claims through the U.S. Equal Employment Opportunity Commission (EEOC) first, and it gives you a startlingly short window to start: as few as 180 calendar days from the discriminatory act.
That administrative step is called filing a "charge of discrimination." Understanding what the charge does, when it must be filed, and what happens afterward is the difference between preserving a claim and losing it before any court ever hears it.
Key takeaways
- Federal anti-discrimination laws generally cover employers with 15 or more employees (20 or more for age discrimination claims).
- A charge must normally be filed within 180 calendar days of the discriminatory act, extended to 300 days where a state or local agency enforces a comparable anti-discrimination law.
- Filing a charge is a prerequisite to suing under Title VII, the ADA, and related statutes — skipping it usually forfeits the claim.
- After 180 days, you can request a Notice of Right to Sue; once it arrives, you have only 90 days to file a lawsuit.
- Retaliation for complaining about discrimination is itself illegal, even if the underlying complaint ultimately fails.
What counts as illegal discrimination
Not every unfair decision breaks the law. An employer may generally be arbitrary, play favorites, or make bad business calls. Discrimination becomes illegal when a term or condition of employment — hiring, pay, promotion, discipline, firing, harassment — is affected because of a legally protected characteristic.
The main federal statutes the EEOC enforces protect against discrimination based on:
- Race, color, religion, sex, and national origin (Title VII of the Civil Rights Act of 1964; "sex" includes pregnancy, sexual orientation, and gender identity);
- Age 40 and over (Age Discrimination in Employment Act);
- Disability, including failure to provide reasonable accommodation (Americans with Disabilities Act);
- Genetic information (GINA); and
- Sex-based pay differences for substantially equal work (Equal Pay Act).
Harassment is a form of discrimination when it is severe or pervasive enough to create a hostile work environment, and whether the employer is on the hook often turns on what it did once it knew — which is why a complaint channel that works and an investigation that follows it carry legal weight and not just HR value. Retaliation — punishing a worker for reporting discrimination, filing a charge, or participating in an investigation — is a separate violation and is the most frequently filed basis in EEOC charges. Pay-related discrimination can also overlap with the wage rules covered in our wage and hour law guide.
Who is covered — employers and workers
Title VII, the ADA, and GINA apply to private employers with 15 or more employees; the ADEA requires 20 or more. Employment agencies and unions are covered too, and state and local governments are included. Smaller employers often remain subject to state anti-discrimination laws with lower thresholds — some reach employers with a single employee — so a claim that fails the federal headcount may still live under state law.
Only employees and applicants are protected by these statutes; genuine independent contractors generally are not. If your status is disputed, the analysis in our article on how worker classification tests work becomes the threshold question of the whole case.
The deadlines: 180 days, 300 days, and the exceptions
The EEOC's time-limit rules are strict and rarely extended:
- 180 calendar days from the day the discrimination took place is the default.
- 300 calendar days applies where a state or local agency enforces a law prohibiting discrimination on the same basis — true in most states.
- Age claims: the extension to 300 days applies only if a state law and state enforcement agency exist; a local ordinance alone does not extend the deadline.
- Each act has its own clock. A discriminatory demotion and a later discriminatory firing are separate events with separate deadlines. Ongoing harassment is treated differently: file within 180/300 days of the last incident, and earlier incidents of the same hostile environment can be considered.
- Equal Pay Act claims follow their own track — two years from the last discriminatory paycheck (three for willful violations) — and can go directly to court without an EEOC charge.
- Federal employees use an entirely different process and must contact their agency's EEO counselor within 45 days.
Watch the deadline: Internal complaints, HR investigations, and settlement talks do not pause the clock. Filing a union grievance does not pause it either. If you are pursuing internal channels as the deadline approaches, file the charge anyway — you can always withdraw it later.
Filing the charge
The EEOC accepts charges through several routes described on its filing page: the online EEOC Public Portal (where you submit an inquiry, schedule an intake interview, and then file), in person at one of its 53 field offices, or by mailed letter. You can call 1-800-669-4000 to start the process, though a charge cannot be completed by phone alone. In states with their own Fair Employment Practices Agencies, filing with the state agency is usually "dual-filed" with the EEOC automatically.
A valid charge needs your contact information, the employer's name, address, and approximate employee count, a description of what happened and when, the basis you believe motivated it, and your signature. You do not need evidence in hand, a lawyer, or a filing fee to submit a charge.
What happens after you file
- Notice to the employer. The EEOC notifies the employer that a charge has been filed, typically within days. Retaliation protections attach immediately.
- Mediation (optional). Many charges are routed to free, voluntary mediation. If both sides agree and reach a settlement, the charge closes. If not, the charge moves to investigation.
- Investigation. An investigator may request a written position statement from the employer, documents, and interviews. Investigations commonly take many months; you should allow the agency at least 180 days.
- Determination. If the EEOC finds reasonable cause to believe discrimination occurred, it attempts conciliation — a voluntary settlement. If conciliation fails, the agency may sue on your behalf (or refer the case to the Department of Justice for public employers), though it litigates only a small fraction of charges.
- Notice of Right to Sue. If the EEOC cannot determine a violation, or you request the notice after 180 days, it issues a Notice of Right to Sue. From the day you receive it, you have 90 days to file a lawsuit, as explained on the EEOC's lawsuit page. Miss that window and the claim is almost always gone.
What a successful claim can recover
Remedies aim to put the worker where they would have been absent discrimination: back pay and lost benefits, reinstatement or front pay, and out-of-pocket costs. Compensatory damages for emotional harm and punitive damages are available under Title VII and the ADA, but federal law caps those amounts based on employer size. Attorney's fees are generally recoverable by prevailing employees. Employers may also be ordered to change policies, train staff, or post notices.
Many discrimination disputes end not in litigation but in negotiated exits. If your employer offers money in exchange for a release of claims, the terms deserve careful reading — our guide to termination and severance agreements explains what those releases waive and what they cannot.
Frequently asked questions
Can I be fired for filing an EEOC charge?
Firing or punishing you for filing a charge is illegal retaliation, and retaliation claims often succeed even when the underlying discrimination claim does not. If it happens, document everything and report it to the EEOC promptly — retaliation after a charge can be added to the existing case.
Do I need a lawyer to file a charge?
No. The charge process is designed for individuals, there is no fee, and EEOC staff assist with intake. That said, a lawyer can help frame the charge, preserve state-law claims, evaluate settlement offers, and act quickly once a right-to-sue notice starts the 90-day clock.
What if my employer has fewer than 15 employees?
Federal law likely will not reach it (20 employees for age claims), but most states prohibit discrimination at lower thresholds, sometimes covering all employers. Check your state's fair employment agency. Deadlines and procedures under state law differ from the EEOC's, and are sometimes more generous.
Can I skip the EEOC and just sue?
Generally not for Title VII, ADA, ADEA, or GINA claims — a charge is a legal prerequisite. The main exception is the Equal Pay Act, which allows direct suits within its two- or three-year window. Some state-law claims also permit direct suits, which is one reason parallel state filings are common.
Where to go from here
Start with the calendar: identify the date of each adverse act and count forward 180 and 300 days. Then preserve evidence — emails, performance reviews, pay records, names of witnesses — before access disappears. File through the EEOC Public Portal or your state agency well before the deadline, and treat every later notice from the agency as time-sensitive.
Discrimination law sits alongside the rest of workplace law: classification, pay, and separation rules all interact with it. For the broader picture, browse our employment law topic hub, and remember that this article is general information, not legal advice about any specific situation.
