How Long Do I Have to Sue My Employer? Deadlines and Tolling

How long you have to sue your employer runs anywhere from 30 days to six years, and the clock that applies depends entirely on what happened and which law covers it. These deadlines, called statutes of limitations, are enforced strictly. Miss yours by a single day and your claim is gone, no matter how strong the facts.

Discrimination, Harassment, and Retaliation Claims

If your claim is discrimination, harassment, or retaliation under Title VII, the Americans with Disabilities Act, or the Genetic Information Nondiscrimination Act, you cannot go straight to court. Federal law requires you to first file a charge of discrimination with the Equal Employment Opportunity Commission.¹ Skip that step and a court will dismiss the case before it starts.

You have 180 calendar days from the discriminatory incident to file the charge. The deadline extends to 300 days if your state has its own anti-discrimination agency enforcing a similar law.² Most states do, so the 300-day window applies across much of the country.

The 90-Day Right-to-Sue Deadline

Once the EEOC finishes its process, or after 180 days if you don’t want to keep waiting, you can request a Notice of Right to Sue.³ From the moment you receive that notice, you have exactly 90 days to file your lawsuit in court.⁴ Courts enforce this deadline rigidly.

This is where people get tripped up. The 90-day clock starts when you’re considered to have received the notice, not when you actually opened the envelope or the email. Check your mail and inbox relentlessly after you file. A missed notice functions the same as a missed deadline.

Age Discrimination Works a Little Differently

The Age Discrimination in Employment Act uses the same 180- or 300-day charge deadline.⁵ The difference: you don’t have to wait for a right-to-sue letter. Once 60 days have passed since you filed your charge, you can go ahead and sue. If a right-to-sue notice does arrive, though, you must file within 90 days of receiving it, just like Title VII.¹

One wrinkle for age claims: the 300-day window only applies if your state has a law prohibiting age discrimination specifically and a state agency enforcing it. A local ordinance alone isn’t enough, and the deadline stays at 180 days.²

Race Discrimination Under Section 1981

Race claims have an alternative path that many people miss. Under 42 U.S.C. § 1981, you can file a race discrimination lawsuit directly in federal court without filing an EEOC charge at all. The statute of limitations is four years. This route only covers race-based claims, but for those claims it can be a lifeline after the EEOC deadline has passed.

Pay Discrimination and the Ledbetter Reset

Pay discrimination used to be one of the hardest claims to bring on time, because the original decision to underpay might have happened years before anyone found out. The Lilly Ledbetter Fair Pay Act of 2009 changed that. Every paycheck reflecting discriminatory pay is treated as a new violation, resetting the 180- or 300-day EEOC clock each time.⁶ The rule covers Title VII, ADEA, and ADA pay claims. If you’ve just learned you’ve been paid less than colleagues for a discriminatory reason, your deadline runs from your most recent paycheck, not from whenever the employer first set your salary lower.

Unpaid Wages and FMLA

If your employer owes you unpaid overtime or minimum wages under the Fair Labor Standards Act, you have two years from the violation to sue. That stretches to three years if you can show the violation was willful, meaning the employer knew what it was doing or showed reckless disregard for the law.⁷

Family and Medical Leave Act claims follow the same pattern: two years from the last event that violated the law, three years if willful.⁸ Neither FLSA nor FMLA lawsuits require a prior agency filing. You can go straight to court.

Whistleblower and Safety Retaliation Claims

Retaliation for reporting safety violations or corporate fraud comes with some of the shortest deadlines in employment law.

Workplace safety complaints under the Occupational Safety and Health Act: 30 days to file a retaliation complaint with OSHA.⁹
Corporate fraud whistleblowing under the Sarbanes-Oxley Act: 180 days from the violation, or from when you became aware of it, to file with the Department of Labor.¹⁰
Union-related retaliation under the National Labor Relations Act: six months to file an unfair labor practice charge with the NLRB.¹¹

The 30-day OSHA window catches people out more than almost any other. If you’ve been fired or disciplined after raising safety concerns, treat it as an emergency and contact OSHA the same week.

Federal Government Employees

If you work for a federal agency, none of the private-sector deadlines apply. You must first contact an Equal Employment Opportunity counselor within your own agency within 45 days of the discriminatory event.¹² That 45-day window is one of the tightest deadlines in employment law, and many federal employees miss it because they never knew it existed.

After counseling, you then have 15 days from the counselor’s notice to file a formal administrative complaint with your agency’s EEO office.¹³ The 45-day deadline can be extended if you weren’t notified of the time limits, didn’t know the discriminatory act had occurred, or were prevented from contacting a counselor by circumstances outside your control.¹²

Employment Contracts and Benefits

Breach-of-contract claims run on state-law deadlines, and the range is wide. For written contracts most states give somewhere between four and ten years, though a few set the bar as low as three years or as high as fifteen. Oral contracts are shorter across the board. Because the number depends entirely on your state, check your state’s specific statute of limitations for contracts before assuming you have time.

Employee benefits governed by ERISA have their own framework. A claim for breach of fiduciary duty must be filed within six years of the last act that constituted the breach, or within three years of the date you gained actual knowledge of it, whichever comes first. If the breach involved fraud or concealment, the deadline extends to six years from the date you discovered the violation.¹⁴ Your plan documents may impose a contractual limitations period shorter than what the statute allows, so read them.

When the Clock Actually Starts

Knowing your deadline requires knowing when the clock started, and that’s not always the day the employer did something wrong.

The Discovery Rule

When the harm isn’t obvious right away, the statute of limitations may not begin until you knew or reasonably should have known about the injury. This comes up most often with concealed fraud or hidden pay discrimination, where you had no way of knowing something was wrong until evidence surfaced. Courts expect reasonable diligence, though. If a judge decides someone in your position should have spotted the problem earlier, the clock may have started running before you actually found out.

Constructive Discharge

If your employer made working conditions so intolerable that you felt forced to resign, that’s called constructive discharge, and it’s treated like a firing for statute-of-limitations purposes. The Supreme Court held in Green v. Brennan that the filing deadline runs from the date you give notice of your resignation, not the date of the employer’s last discriminatory act.¹⁵ The resignation usually happens after the underlying conduct, so this typically buys you time.

Hostile Work Environment and Continuing Violations

A hostile work environment usually builds through a pattern rather than a single incident. In National Railroad Passenger Corp. v. Morgan, the Supreme Court held that a hostile work environment charge is timely as long as at least one act contributing to the claim falls within the 180- or 300-day filing window. Earlier incidents that would otherwise be time-barred can still be included as part of the same pattern. The rule is limited to hostile work environment claims. Discrete acts such as a termination, demotion, or denial of a transfer each carry their own individual deadline.¹⁶

When a Deadline Can Be Paused

Courts can pause or extend a statute of limitations in narrow circumstances through two related doctrines.

Equitable Tolling

Equitable tolling applies when you were unaware of the facts that should have prompted you to file, through no fault of your own. The deadline may be paused if you were a minor at the time of the violation, were mentally incapacitated, or were reasonably unaware of the EEO process. The extension lasts a reasonable period after the barrier is removed.¹⁷ Courts scrutinize these claims closely. You need real evidence that something prevented you from acting, not just that you didn’t get to it.

Equitable Estoppel

Equitable estoppel is different. It applies when you knew about the potential claim but the employer’s own misconduct caused you to delay. Examples include an employer promising not to raise the deadline as a defense, threatening retaliation if you filed, concealing evidence, or assuring you that internal grievance procedures would resolve the issue.¹⁷ Under estoppel, the filing period starts running when you discovered or should have discovered the employer’s misconduct. Both doctrines are exceptions, not entitlements, and courts grant them sparingly.

What to Do Now

With some deadlines as short as 30 days, the most useful thing you can do is talk to an employment lawyer as soon as you suspect something is wrong. Statutes of limitations don’t pause while you research the law, weigh your options, or try to work things out internally. Every day of delay is a day closer to a deadline you may not know applies. A consultation doesn’t commit you to filing anything, but it does tell you exactly how much time you have and which clock is running.
