An Employee Just Complained About Harassment: What Do I Do?

Quick Answer: When an employee reports a harassment complaint, listen without judgment, document the complaint immediately, assess whether interim separation is needed, conduct a prompt impartial investigation, make a finding, take corrective action, and close the loop with the complainant. Most importantly, watch for retaliation after the complaint is closed. Here's the full step-by-step process.

An employee comes to you. They say a coworker, or maybe their manager, has been making comments that made them uncomfortable. Or touched them without consent. Or said something at a team dinner that crossed a line.

What you do in the next 24 hours matters more than almost anything else that follows. The biggest mistakes employers make in harassment situations are not usually the original incident. They are what happens afterward: the dismissive response, the incomplete investigation, the retaliation that wasn’t even intentional.

Here is what to do.

Step 1: Listen and Take It Seriously

When an employee comes to you with a harassment complaint, your first job is to listen without judgment and without minimizing what you’ve heard. Do not say “I’m sure they didn’t mean it that way.” Do not say “That doesn’t sound like something they would do.” Do not offer your personal opinion about the accused.

Your response in this first conversation sets the tone for the entire process. Not every complaint rises to the level of a formal harassment investigation. Read about when an employee complaint about a coworker becomes an HR issue to help assess what you are dealing with. Employees who feel dismissed at the first step either disengage from the process entirely or escalate directly to an outside agency, and the EEOC does not look kindly on employers who discouraged reporting.

What to say instead: “Thank you for telling me. I want you to know I take this seriously and I’m going to look into it.” Then actually do that.

Step 2: Document the Complaint Immediately

As soon as the conversation ends, ideally before you do anything else, write down everything you were told. Date, time, who came to you, what they said, who was allegedly involved, when the incidents occurred, whether there were witnesses. Use their words as much as possible, not your interpretation.

This document is the foundation of your investigation file. It also protects you. If the situation later becomes a legal matter, your contemporaneous notes, meaning notes written at the time, not reconstructed later, carry significant evidentiary weight.

Step 3: Notify HR (or Get Help)

If you have an HR department or HR contact, loop them in immediately. If you are the HR person, or if you are a small business owner without HR support, this is the moment to consider whether you need outside help.

Harassment investigations have specific legal requirements and process standards. Getting this wrong, like interviewing witnesses in the wrong order, confronting the accused before documenting the complaint, or failing to maintain confidentiality, can significantly increase your legal exposure. If you don’t have in-house HR expertise, an employment attorney or HR consultant for an hour of guidance right now is worth far more than it costs.

Step 4: Assess Whether Interim Separation Is Needed

Before you begin a formal investigation, consider whether the complainant and the accused need to be separated while the process plays out. In serious situations like allegations of physical contact, a direct reporting relationship, or conduct that is ongoing, allowing the two parties to continue working closely together is both harmful to the complainant and legally risky for you.

Options include temporarily shifting schedules, reassigning one party to a different project, or in the most serious cases, placing the accused on paid administrative leave pending investigation. The key principle: the burden of any interim separation should fall on the accused, not the complainant. Moving the person who reported the issue to a less desirable shift or location looks like retaliation even if that is not your intent. Harassment complaints sometimes arise from workplace relationships that have gone wrong. See our guide on how to handle employees who are dating before a complaint occurs.

Step 5: Conduct a Prompt, Impartial Investigation

A proper harassment investigation involves interviewing the complainant, the accused, and any relevant witnesses separately and confidentially. It also involves reviewing any relevant documentation like emails, texts, performance records, and prior complaints.

The investigator should have no personal relationship with either party. If that is not possible in a small organization, consider bringing in an outside investigator.

Document every interview. Keep your notes factual and objective. Do not share interview details between parties. Maintain strict confidentiality, and tell witnesses that the matter is confidential and that they should direct any questions to HR.

The investigation should be completed as quickly as thoroughness allows. Weeks-long delays without communication to the complainant feel like inaction and erode trust in the process.

Step 6: Make a Finding and Take Action

At the end of the investigation, you need to make a determination: did the conduct violate your policy or not? This does not need to be a criminal standard of proof. The question is whether, based on the evidence available, the conduct more likely than not occurred and whether it meets the standard of your harassment policy.

If the finding is that a violation occurred, take prompt corrective action proportionate to the severity. Corrective action ranges from a formal written warning and mandatory training to demotion, reassignment, or termination depending on the conduct.

If the finding is inconclusive or insufficient to substantiate the complaint, document that determination and your reasoning. Close the file with a note that you will monitor the situation.

Step 7: Close the Loop With the Complainant Carefully

You are not required to share the details of your investigation or its findings with the complainant. But you should communicate that you completed the investigation and took appropriate action. Leaving the reporting employee in complete silence is itself a problem, and it signals that nothing happened and discourages future reporting.

A simple, appropriate close: “I want to let you know that we completed our review of your concern and have taken appropriate action. I’m not able to share the specifics, but I want to reiterate that we take these matters seriously. Please come to me immediately if anything else occurs.”

The One Thing That Makes Everything Worse: Retaliation

Retaliation against an employee for making a harassment complaint, even an unsubstantiated one, is illegal. And retaliation does not have to be dramatic to be real. Suddenly not including the complainant in meetings. Giving them a negative performance review right after the complaint. Passing them over for a project they would normally have received.

Monitor the situation actively after the complaint is closed. If the complainant’s work experience noticeably worsens after they reported, that is a problem you need to address with the people responsible for it.

The Real Lesson: Policy Before Incident

The single best thing you can do to manage harassment complaints well is to have a clear, written anti-harassment policy before any complaint occurs. A policy that names who employees report to, explains the investigation process, and explicitly prohibits retaliation does several things at once: it tells employees you take this seriously, it gives managers a process to follow when something happens, and it gives you legal protection by demonstrating that you had a policy and followed it. If the situation involves an ongoing conflict rather than a clear harassment complaint, see our guide on handling two employees who are in a conflict.

Frequently Asked Questions

What should I do first when an employee reports harassment? Listen without minimizing or offering opinions about the accused. Your first response sets the tone for everything that follows. Say "Thank you for telling me. I take this seriously and I'm going to look into it", then follow through immediately. Document the complaint in writing before doing anything else.

Am I required to investigate every harassment complaint? Yes. Once an employer receives notice of a harassment complaint, you have a legal obligation to investigate promptly and impartially. Failing to investigate (or conducting a superficial investigation) significantly increases your legal exposure, regardless of whether the complaint is ultimately substantiated.

Can I keep a harassment investigation confidential? You should make every reasonable effort to maintain confidentiality, but you cannot guarantee absolute confidentiality because a proper investigation requires interviewing witnesses. Tell all parties that the matter is confidential and that they should not discuss it with coworkers. Document that you communicated this expectation.

What if the harassment complaint is against the owner or a senior leader? This is the situation that most requires outside help. An internal investigation where the accused is in a position of authority over the investigator is compromised from the start. Bring in an outside HR consultant or employment attorney to conduct the investigation. This protects both the complainant and the business.

What is retaliation and how do I prevent it? Retaliation is any adverse action taken against an employee because they made a harassment complaint, including negative performance reviews, schedule changes, exclusion from meetings, or termination. It does not have to be intentional to be illegal. After closing a harassment investigation, actively monitor the complainant's work experience and address any changes in how they are being treated by managers or coworkers.

Does my business need an anti-harassment policy even if I only have a few employees? Yes. Federal anti-harassment law applies to employers with 15 or more employees, but many state laws apply to smaller employers, and having a clear written policy protects your business regardless of size. A policy that names reporting contacts, explains the investigation process, and prohibits retaliation demonstrates that you took the issue seriously, which matters significantly if a complaint ever escalates to an agency or court.
