Suing an employer is a multi-step legal process that follows a specific sequence regardless of what the employer did wrong. The sequence matters: skip or reverse the steps and you may permanently lose your right to pursue the claim in court. This guide covers the procedural roadmap for the most common employment lawsuits — discrimination, retaliation, wage theft, and harassment — from the moment of the incident through filing in federal or state court.
This guide does not cover workers’ compensation claims (which follow a separate administrative process) or union grievances (which are governed by collective bargaining agreements). It also does not constitute legal advice for any specific situation.
Key Takeaways
- Most federal employment discrimination claims require filing a charge with the EEOC before you can sue in court — and that charge must typically be filed within 180 to 300 days of the wrongful act, not years later
- The cost of suing an employer varies widely, but many employment attorneys take discrimination and retaliation cases on contingency — no fee unless you recover — because federal fee-shifting statutes require losing employers to pay prevailing plaintiffs’ attorney fees in certain cases
- Wage and hour claims (unpaid overtime, minimum wage violations) can sometimes be filed directly in federal court without an administrative charge, though state law deadlines still apply
Step 1: Identify the Legal Basis for Your Claim
The first question is not “did my employer treat me unfairly?” — it is “did my employer violate a specific federal or state law?” The legal basis determines which agency handles the complaint, which deadlines apply, and what remedies are available.
The most common federal employment statutes that generate employer lawsuits include Title VII of the Civil Rights Act of 1964 (race, color, religion, sex, national origin), the Age Discrimination in Employment Act (ADEA, workers age 40 and over), the Americans with Disabilities Act (ADA), the Equal Pay Act, the Family and Medical Leave Act (FMLA), and the Fair Labor Standards Act (FLSA) for wage and hour matters.
State employment laws often parallel these federal statutes but frequently offer broader protections — shorter proof requirements, lower threshold employers (federal Title VII applies to employers with 15 or more employees; many state equivalents apply to employers with 5 or fewer), and longer statutes of limitations.
Identifying which law governs determines what you do next.
Step 2: Gather and Preserve Evidence Immediately
The window between the incident and formal legal action is when evidence disappears most rapidly. Employees who wait months before thinking about documentation often discover that emails have been purged, witnesses have been transferred, and records have been overwritten.
The categories of evidence that typically matter most in employment cases:
Written records: Emails, text messages, performance reviews, disciplinary notices, offer letters, the employee handbook, pay stubs, and any written communications that show what was said and when. Download or screenshot anything accessible from your personal devices before your access is terminated, if it hasn’t been already.
Your own contemporaneous notes: A dated personal log of incidents — what was said, who was present, what happened immediately before and after — carries more weight in litigation than reconstructed recollections. Write these as events occur.
Witness information: Names and contact information of colleagues who witnessed relevant events. Witnesses change jobs, relocate, and become hard to reach quickly. Record this information now.
HR complaints you made: If you reported the conduct to HR, keep copies of what you submitted and any written responses. The employer’s knowledge of the conduct and failure to address it is often a central issue.
Step 3: File an Internal Complaint (If You Haven’t Already)
Many employment laws require, or at least benefit significantly from, the employee having reported the conduct through the employer’s internal processes before escalating externally. There are two practical reasons for this.
First, for some claims — particularly hostile work environment harassment under Title VII — employers can assert an affirmative defense (the Faragher-Ellerth defense) arguing that the employee unreasonably failed to use available internal complaint procedures. Failing to make an internal complaint can give the employer a viable defense it wouldn’t otherwise have.
Second, the employer’s response to an internal complaint becomes evidence. An employer who receives a harassment complaint and retaliates against the complainant, or ignores it entirely, has created a substantially stronger case than if they had never been put on notice.
File internal complaints in writing, not just verbally, and keep a copy.
Step 4: File an Administrative Charge (Required for Most Federal Discrimination Claims)
For claims under Title VII, the ADA, the ADEA, and most other federal anti-discrimination laws, an employee cannot go straight to federal court. The law requires filing a charge of discrimination with the Equal Employment Opportunity Commission (EEOC) first. According to the EEOC’s guidance on filing a charge of discrimination, the EEOC is required to accept charges alleging employment discrimination, and the laws it enforces (except the Equal Pay Act) require you to file a charge before filing a lawsuit for unlawful discrimination.
The EEOC charge must be filed within 180 calendar days of the discriminatory act. This deadline is extended to 300 calendar days if a state or local agency enforces a law prohibiting the same type of discrimination — which is the case in most states. Missing this deadline generally forfeits the federal discrimination claim permanently.
The charge can be filed online through the EEOC Public Portal, by phone at 1-800-669-4000, by mail, or in person at one of the EEOC’s 53 field offices. EEOC services are free and you do not need an attorney to file a charge.
What happens after the charge is filed: The EEOC notifies the employer within 10 days. The EEOC may offer mediation, conduct an investigation, or issue a determination. If the EEOC closes the case without finding a violation, it issues a “Dismissal and Notice of Rights” — commonly called the Right to Sue letter. Once you receive it, you have 90 days to file a lawsuit in federal court. That 90-day window is a hard deadline.
Wage and hour claims under the FLSA generally do not require an EEOC charge. Claims for unpaid overtime or minimum wage violations can be filed directly in federal court, though the EEOC’s filing charge page notes that Equal Pay Act claims specifically have different timelines.
Step 5: Consult an Employment Attorney
Employment law litigation is procedurally complex and strategically demanding. Consulting an attorney early — before or immediately after filing an EEOC charge — helps avoid common mistakes that compromise otherwise valid claims.
Many employment attorneys who handle discrimination, harassment, and retaliation cases work on contingency: no fee unless the case recovers money. Federal fee-shifting statutes under Title VII, the ADA, the ADEA, and the FMLA require losing employers to pay reasonable attorney fees to the prevailing plaintiff. This makes it financially viable for attorneys to take meritorious employment cases on contingency even when the individual damages are modest.
Initial consultations are typically free. An attorney can evaluate whether the facts support a viable claim, identify which legal theories are strongest, flag deadlines you may not be aware of, and advise on whether settlement discussions make sense before litigation begins.

Step 6: Attempt Mediation or Settlement
The majority of employment lawsuits settle before trial. Many settle during the EEOC process, before a lawsuit is ever filed. Settlement has practical advantages for both sides: lower cost, faster resolution, and privacy (court filings are public; settlement agreements typically are not).
The EEOC’s mediation program is free to both parties, confidential, and can resolve charges quickly. Participation is voluntary but worth considering if both sides are willing — mediation statistics from the EEOC show that a significant percentage of mediated charges result in resolution satisfactory to the charging party.
Once a lawsuit is filed, formal settlement discussions typically happen through mediation with a private mediator or through court-ordered settlement conferences. Settlement negotiations can occur at any point in the litigation.
Step 7: File the Lawsuit
If the EEOC process doesn’t resolve the matter and you receive a Right to Sue letter, the lawsuit is filed in federal district court within the 90-day window. The complaint sets out the factual allegations and the legal claims. The employer receives the complaint and has a deadline to respond.
After filing, the case moves through discovery — the formal exchange of documents and depositions — before reaching motions practice and, ultimately, trial. Most employment cases settle during or after discovery and before trial.
State law claims that parallel the federal claims (state anti-discrimination statutes, public policy tort claims, breach of contract) can often be filed in state court without the EEOC charge prerequisite, though they have their own statutes of limitations that vary significantly by state. Some attorneys file both federal and state claims simultaneously to preserve all options.
When to Hire an Attorney vs. Proceeding Pro Se
Situations where professional representation is practically necessary:
- Federal court litigation, including all cases that required an EEOC charge, involves complex procedural rules that significantly disadvantage unrepresented parties
- Cases with disputed facts (the employer denies the conduct occurred, or disputes the discriminatory motive) require litigation skills most people don’t have
- Cases involving damages above small claims limits, where the potential recovery justifies the cost of representation
- Cases where the employer’s legal department is already involved — a represented employer against a pro se plaintiff is an unequal contest
Situations where limited-scope representation or self-help may be workable:
- Filing an EEOC charge (the EEOC process itself is designed to be accessible without an attorney)
- Simple wage claims for undisputed amounts in jurisdictions with accessible small claims or labor commission processes
- Consulting an attorney for advice while handling some administrative steps yourself

How Long Does Suing an Employer Take?
The EEOC administrative process alone typically takes six months to two years from charge filing to Right to Sue notice. Federal court litigation from filing to resolution (whether settlement or trial verdict) typically takes one to three years for cases that don’t settle early. Cases that settle quickly — during EEOC mediation or shortly after a lawsuit is filed — can resolve in months.
For a realistic picture of civil litigation timelines generally, how long does a lawsuit take covers the typical phases and what drives variation in duration.
FAQ
Do I have to use the EEOC before I can sue my employer? For most federal discrimination claims under Title VII, the ADA, and the ADEA, yes. The EEOC charge is a jurisdictional prerequisite to filing a federal lawsuit. For wage and hour claims under the FLSA, no — those can go directly to court. State law claims vary by state.
Can I be fired for filing an EEOC charge? Retaliation against an employee for filing an EEOC charge is separately illegal under federal law, even if the underlying charge ultimately isn’t found to have merit. Filing a charge doesn’t protect against all adverse employment actions, but it does create an additional legal claim if the employer retaliates.
What damages can I recover if I win? Recoverable damages vary by claim type. Discrimination claims typically allow back pay, front pay, compensatory damages (including emotional distress), and punitive damages in cases of egregious employer conduct, subject to statutory caps based on employer size. Wage claims recover unpaid wages plus an equal amount as liquidated damages, plus attorney fees. The EEOC charge process itself doesn’t award damages — damages come from court judgments or negotiated settlements.
What if my employer is very small? Federal employment laws have minimum employer size thresholds. Title VII and the ADA apply to employers with 15 or more employees. The ADEA applies to employers with 20 or more employees. The FLSA applies to most employers. State equivalents often have lower thresholds — some state anti-discrimination laws apply to employers with as few as one or four employees. Small employer size may mean federal law doesn’t apply, but state law may still provide remedies.
Can I sue a former employer after I’ve left the company? Yes, provided you act within the applicable deadlines. The EEOC charge deadline runs from the discriminatory act, not from your last day of employment. State law limitations periods similarly run from the underlying event. Leaving the company doesn’t restart the clock — it continues from when the wrongful conduct occurred.
What’s the difference between the EEOC and a state civil rights agency? Both investigate employment discrimination, but under different laws. Most states have their own civil rights agencies (called Fair Employment Practices Agencies, or FEPAs) that enforce state employment discrimination laws. Filing with the state FEPA is automatically “dual-filed” with the EEOC for purposes of federal law, and vice versa. The practical effect is that you don’t generally need to file with both separately — one filing covers both.
