If a customer, client, patient, vendor, or any other non-employee harasses you at work because of your race, sex, religion, national origin, or another protected characteristic, your employer can be held legally responsible. Third-party harassment employer liability under federal law turns on a single question: did management know or should it have known about the conduct, and did it take prompt corrective action? If the answer is no, the employer is on the hook, even though the harasser doesn’t work there.
When Your Employer Becomes Legally Responsible
The rule comes from the EEOC’s regulation at 29 C.F.R. § 1604.11(e), which makes employers responsible for harassment by non-employees in the workplace when management knew or should have known about it and failed to take immediate and appropriate corrective action. In deciding these cases, the EEOC weighs how much control the employer actually had over the non-employee’s behavior.1eCFR. 29 CFR 1604.11 – Sexual Harassment The EEOC’s enforcement guidance extends the same principle beyond sexual harassment: employers are liable for harassment by non-employees when management knew or should have known of the misconduct and cannot show it took immediate corrective action.2U.S. Equal Employment Opportunity Commission. Enforcement Guidance – Vicarious Liability for Unlawful Harassment by Supervisors
This is a negligence standard. The employer doesn’t have to intend or approve of the harassment. It just has to act reasonably once it’s on notice.
The Tenth Circuit’s decision in Lockard v. Pizza Hut, Inc. shows how this plays out. Rena Lockard, a waitress, told her shift manager that two male customers had been making sexually offensive comments and that she didn’t want to serve them. The manager told her, “You wait on them. You were hired to be a waitress. You waitress.” When Lockard returned to the table, one customer grabbed her by the hair, then grabbed her breast and put his mouth on it. She quit. A jury found the employer liable, and the appeals court affirmed, holding that employers can be liable for customer harassment under a negligence theory when management-level employees knew about the conduct and did nothing—whether the fix would have been reassigning another server, serving the customers themselves, or asking them to leave.3Justia Law. Lockard v. Pizza Hut, Inc., 162 F.3d 1062
The lesson is blunt. A policy in the handbook isn’t enough. Courts look at what the employer actually did.
What a Reasonable Response Looks Like
Once the employer knows about the harassment, its response needs to accomplish three things: stop the conduct, correct its effects on you, and prevent it from happening again. The action has to be proportional to the severity of what happened.
Depending on the situation, reasonable steps might include:
- Moving you away from the harasser, without making the reassignment feel like punishment for reporting.
- Refusing to serve or admit the customer or client who caused the problem.
- Changing schedules, routes, or service areas so you no longer encounter the harasser.
- Notifying a vendor’s or contractor’s employer and demanding a different representative.
The measures don’t have to be exactly what you asked for, but they do have to work. And the employer should follow up to confirm the harassment stopped. A single conversation with no follow-through won’t satisfy a court.
Does Federal Law Cover Your Employer?
Title VII of the Civil Rights Act of 1964 applies only to employers with 15 or more employees working each day for at least 20 calendar weeks in the current or preceding year.4U.S. Equal Employment Opportunity Commission. Title VII of the Civil Rights Act of 1964 If you work for a smaller business, federal law won’t reach your situation, but state law often will. Many states set their coverage threshold well below 15 employees, and some apply their anti-discrimination laws to employers of any size. State laws also frequently protect categories Title VII doesn’t explicitly name, such as sexual orientation, gender identity, marital status, or military service status. If your employer falls below the federal threshold, checking your state’s fair employment practice law is the single most important next step.
Retaliation Is Illegal Too
Section 704 of Title VII makes it illegal for an employer to punish anyone for opposing an unlawful employment practice or for filing a charge, testifying, or participating in an investigation.5Office of the Law Revision Counsel. 42 U.S. Code 2000e-3 – Other Unlawful Employment Practices Retaliation isn’t limited to firing. Under the Supreme Court’s standard in Burlington Northern v. White, any action that would discourage a reasonable worker from making a complaint qualifies, including demotion, hardship schedule changes, negative performance reviews, loss of responsibilities, or being frozen out of opportunities.
This matters because reporting a valued client or high-revenue customer can feel professionally risky. The law protects you regardless of the harasser’s economic importance to the business.
How Long You Have to File
Time limits are strict, and the clock starts on the date of the last harassing incident. You have 180 calendar days to file a charge with the EEOC in states without a local anti-discrimination agency, or 300 calendar days if your state has its own fair employment practice agency that enforces a comparable law.6U.S. Equal Employment Opportunity Commission. Time Limits for Filing a Charge Most states have such an agency, so the 300-day window applies to the majority of workers. Weekends and holidays count toward the total, but if the deadline itself falls on a weekend or holiday, you have until the next business day.
In harassment cases, the EEOC will look at all incidents when investigating—even those that occurred before the 180- or 300-day window—as long as the last incident falls within the filing period.6U.S. Equal Employment Opportunity Commission. Time Limits for Filing a Charge Third-party harassment often involves a pattern of escalating behavior over months, and you don’t lose the earlier incidents just because they’re individually time-barred.
Filing a Charge With the EEOC
You have to file a charge with the EEOC before you can sue under Title VII. The process starts with an inquiry through the EEOC’s Public Portal at eeoc.gov. An EEOC staff member will then interview you to see whether your situation falls under the laws the agency enforces. If it does, the staff member prepares a formal charge for you to review and sign.7U.S. Equal Employment Opportunity Commission. How to File a Charge of Employment Discrimination
You can also start in person at any of the EEOC’s 53 field offices (walk-ins are accepted, though appointments are available through the portal) or by calling 1-800-669-4000. The EEOC doesn’t take charges over the phone, but a representative will walk you through the basics.7U.S. Equal Employment Opportunity Commission. How to File a Charge of Employment Discrimination
After filing, the EEOC may offer voluntary mediation with a neutral mediator; nothing said in mediation can be used later in an investigation if it fails.8U.S. Equal Employment Opportunity Commission. Questions and Answers About Mediation If mediation doesn’t resolve the charge, or either party declines it, the charge goes to an investigator. If the investigation finds evidence of discrimination, the EEOC first tries conciliation with the employer. If that fails, the EEOC can sue on your behalf, though in practice it litigates only a fraction of cases. More often, you’ll receive a Notice of Right to Sue, which lets you file your own lawsuit in federal or state court.9U.S. Equal Employment Opportunity Commission. Filing a Lawsuit
You can also request a Right to Sue letter before the investigation finishes. If more than 180 days have passed since you filed your charge, the EEOC must issue the notice on request. Once you receive it, you have exactly 90 days to file a lawsuit. No extensions.9U.S. Equal Employment Opportunity Commission. Filing a Lawsuit
What You Can Recover
A successful third-party harassment claim can produce several types of relief. Back pay covers wages you lost because of the harassment or the employer’s failure to address it. Front pay compensates for future lost earnings when reinstatement isn’t practical, for instance when the working relationship has become too hostile to resume. Courts can also order injunctive relief, such as requiring the employer to change its policies, stop a discriminatory practice, or make sure you have no future contact with the harasser.10U.S. Equal Employment Opportunity Commission. Remedies – Chapter 11
Compensatory damages cover emotional distress, mental anguish, and other non-financial harm. Punitive damages punish employers who acted with reckless indifference to your rights. Federal law caps the combined total of compensatory and punitive damages based on employer size:11Office of the Law Revision Counsel. 42 U.S. Code 1981a – Damages in Cases of Intentional Discrimination
- 15 to 100 employees: $50,000
- 101 to 200 employees: $100,000
- 201 to 500 employees: $200,000
- More than 500 employees: $300,000
These caps apply per complaining party to claims of intentional discrimination under Title VII. They don’t cap back pay or front pay, which are equitable remedies calculated separately. State laws may allow additional or higher damages, so the federal cap isn’t always the ceiling.
Document Everything, Starting Today
Strong documentation is what separates cases that move forward from cases that stall. Record the date, time, location, what was said or done, and who else was present. Do this the same day. Memory degrades fast, and contemporaneous notes carry far more weight than reconstructed timelines.
Save any digital evidence: text messages, emails, voicemails, social media posts, security camera footage. For emails, save the full message as a PDF with the header information, which contains routing data that can help establish who sent it. Print or screenshot text messages rather than trusting them to stay on your phone. Back everything up to a second location: a personal email account, a USB drive at home, or a cloud folder your employer can’t reach.
Report the harassment through your employer’s internal channels and keep a copy of every report you submit. If you report verbally, send a follow-up email summarizing what you said and to whom. That record is what puts the employer on notice, which is the key element in establishing liability. If the employer’s response is inadequate or nonexistent, that same record becomes central evidence in any EEOC charge or lawsuit.
