How Should Employers Respond to Workplace Harassment Claims

A harassment complaint just landed on your desk. What you do in the next 24 hours will become part of the legal record.

Under California's Fair Employment and Housing Act, courts and the Civil Rights Department evaluate not just what was alleged but how you responded. The California Civil Rights Department published its 2025 Harassment Prevention Guide specifically to clarify what "reasonable steps" look like in practice.

A properly documented response is your strongest legal defense. A poorly handled one can itself form the basis of a claim, independent of what the original complaint alleged.

Here is what you are actually facing, and what to do now.

Why Does California Law Evaluate How You Respond, Not Just What Happened?

Under FEHA, California employers are required to take "immediate and appropriate corrective action" when they know or should know that harassment is occurring. This standard is codified in Government Code section 12940(j) and (k), and it places the employer's response process under legal scrutiny that is separate from the conduct being investigated.

In March 2025, the California Civil Rights Department published a revised Harassment Prevention Guide for California employers. The Guide clarifies what "reasonable steps" look like in practice and identifies three areas employers must prioritize: policy and leadership, reporting and investigations, and remedial action and anti-retaliation. This Guide represents the current standard against which California will measure your response.

California courts have consistently held that the quality and fairness of an employer's investigative process can determine liability on its own terms. An investigation that was delayed, biased, or poorly documented can form the basis of an independent FEHA claim, even when the original harassment allegation lacked sufficient severity to be unlawful on its own.

Your response to the complaint in hand is building your legal defense or eroding it. Employers who want to understand how California measures investigative quality and what a defensible response looks like from a litigation standpoint should review what Backstrom Labor Law's harassment defense practice covers, because the litigation defense and the investigation process cannot be treated as separate exercises.

Title VII of the Civil Rights Act of 1964 and the EEOC set parallel federal standards, but California's FEHA is broader and its enforcement through the CRD operates independently. Employers in California are subject to both, and FEHA generally imposes stricter requirements.

What Should Employers Do the Moment a Harassment Complaint Arrives?

The steps below are sequenced deliberately. Each one protects what comes next.

1. Acknowledge the complaint the same day and confirm to the reporting employee that you have received it and are taking it seriously. Silence in the record reads as indifference.
2. Assess whether immediate protective measures are needed. Depending on the allegations, that may mean separating the parties, adjusting work schedules, modifying reporting lines, or placing the accused on paid administrative leave while the facts are gathered.
3. Issue a document preservation notice immediately. Stop routine deletion of emails, texts, Slack or Teams messages, security footage, performance records, and any communications involving the parties.
4. Keep the initial circle extremely small. Every person who learns about the complaint before you properly structure the investigation is a potential witness with a potential conflict.
5. Communicate anti-retaliation expectations to all supervisors involved. Any change in hours, assignments, or treatment affecting the complainant after a complaint is filed can serve as the basis for a retaliation claim, even when the intent was entirely unrelated to the complaint.
6. Identify whether the accused is a supervisor or a co-worker. This changes your legal exposure immediately.

Three common early mistakes each create separate legal problems before the investigation begins: confronting the accused directly before the investigation starts, telling the complainant you will look into it informally, or waiting to see whether the situation resolves on its own.

Why Does It Matter Whether the Accused Is a Supervisor or a Co-Worker?

Under FEHA, employers are strictly liable for harassment committed by supervisors against subordinates. Strict liability means the employer's knowledge or intent is irrelevant. If a supervisor harassed an employee, the employer is responsible, subject to the affirmative defense discussed in the next section.

For co-worker harassment, liability requires that the employer "knew or should have known" about the conduct and failed to take immediate and appropriate corrective action. That is still a demanding standard, but it turns on awareness rather than automatic responsibility. Knowing which situation you are in changes what you must do first.

How Should Employers Conduct a Legally Defensible Investigation?

Timing matters under California law. Employers must initiate a harassment investigation as soon as reasonably feasible after receiving a complaint. For allegations involving physical conduct or threats of violence, same-day action may be required. For other complaints, contacting the complainant within one or two days and completing the investigation within a few weeks is consistent with California practice. Delays in starting or completing an investigation can independently create liability.

Who conducts the investigation is just as important as when it starts. The investigator must be impartial: someone with no personal stake in the outcome and no relationship that could reasonably appear to bias their conclusions. In California, external workplace investigators must be licensed attorneys or licensed private investigators. When the complaint involves senior leadership, when prior complaints exist about the same individual, or when the matter carries significant litigation exposure, outside legal counsel is the appropriate choice.

Structured interviews are the core of any investigation. Interview the complainant first, then the accused, then any witnesses, in separate sessions. Use open-ended, non-leading questions. Take detailed written notes and retain them. Gather electronic evidence alongside witness accounts: emails, texts, Slack or Teams messages, security footage, and any prior HR complaint logs. The 2025 CRD Harassment Prevention Guide explicitly addresses remote and virtual workplaces, confirming that harassment through electronic communications is subject to the same investigation standards as in-person conduct.

An employer who responds to a complaint with a prompt, documented, impartial investigation is building the record it will need in court. An employer who delays or documents poorly is building the record for the other side.

What Evidentiary Standard Applies to a California Workplace Investigation?

California workplace investigations apply the preponderance of evidence standard. That means the investigator determines whether the alleged conduct more likely than not occurred, sometimes described as "fifty percent plus a feather."

Employers who apply the criminal "beyond a reasonable doubt" threshold create an unrealistically high bar and will have their findings challenged by courts and the CRD. The goal is not certainty. The goal is a well-reasoned, documented, good-faith conclusion based on the evidence gathered.

When credibility is at issue, document the analysis in writing. Relevant factors include consistency of accounts over time, corroborating evidence, witness demeanor, and whether prior complaints exist about the same individual.

What Is the Faragher-Ellerth Defense, and Why Does Every Investigation Build It?

The Faragher-Ellerth affirmative defense allows an employer to avoid or limit liability for supervisor harassment by proving two things: first, that the employer exercised reasonable care to prevent and promptly correct harassment; and second, that the employee unreasonably failed to take advantage of the complaint procedures the employer made available.

California courts have adopted this framework under FEHA for supervisor harassment cases where no tangible employment action was taken against the complaining employee. This defense is one of the most important employer-protection tools available in harassment cases, and it is almost entirely absent from the guidance California employers typically encounter.

The defense carries a critical condition: it is not available when the supervisor's harassment resulted in a tangible employment action against the employee, meaning a termination, demotion, significant pay reduction, or reassignment to materially worse conditions. When a tangible employment action occurs, strict liability applies.

When no tangible employment action occurred, a California employer with written anti-harassment policies, documented training records, accessible reporting channels, and a documented history of handling prior complaints promptly and impartially is in a significantly stronger position. Every properly handled complaint is a building block in the Faragher-Ellerth record.

The employer who never received a complaint is not in a better position than the employer who received one and handled it correctly. The documented record of a properly handled complaint IS the foundation of the Faragher-Ellerth defense.

The consequences of not building that foundation are material. A supervisor harassment case without the Faragher-Ellerth defense available exposes the employer to compensatory damages for the employee's emotional distress and economic losses, and to punitive damages when the conduct reflects conscious disregard for employee rights.

Karin Backstrom has defended California employers in FEHA harassment matters for more than 26 years, including cases where the quality of the employer's investigation process itself was the issue before the CRD and in California courts.

When Karin oversees or conducts a workplace investigation, the record is built with the legal defense in mind from the first day, and attorney-client privilege may protect the investigation findings if the matter escalates to litigation. Backstrom Labor Law's harassment and discrimination defense practice covers the full arc from complaint intake through CRD proceedings and civil litigation.

What Corrective Action Should Employers Take After an Investigation?

Once findings are made, California employers must take prompt corrective action proportional to the severity of the conduct. A formal finding of harassment that results only in a verbal conversation is unlikely to satisfy the "reasonable steps" standard under FEHA or the 2025 CRD Guide.

The employer must tailor corrective action to the findings and address the risk of recurrence directly. Depending on the severity of the conduct, appropriate responses may include additional training, a formal transfer, a written warning, suspension, or termination. Document the decision and the reasoning behind it before implementing.

Consistency matters. Similar conduct should receive similar discipline across the workforce. Disparate treatment of comparable situations creates discrimination exposure independent of the original harassment allegation.

When allegations are not substantiated, document the outcome clearly, assess whether any policy or training gap contributed to the complaint, and follow up with the complainant within a reasonable time to confirm the situation has been resolved. Communicate the outcome to both parties respectfully. Neither needs full investigative detail, but both should understand that the process concluded and that the company took appropriate action.

What Prevention Steps Reduce Future Harassment Claims?

The most effective response to a harassment complaint is having built the right foundation before one arrives. California law requires employers with five or more employees to maintain a written anti-harassment policy explaining how employees can report concerns, how investigations will be conducted, and what corrective action may follow. Employers must distribute the policy and keep it current.

Supervisor training is mandatory under Government Code section 12950.1: two hours of harassment prevention training every two years for supervisors, and one hour every two years for non-supervisory employees. Training must be interactive. New supervisors must complete training within six months of hire or promotion. New non-supervisory employees must complete training within their first 30 days. California's statewide compliance deadline of January 1, 2027 applies across all covered employers.

The 2025 CRD Guide emphasizes that policies and training alone are not sufficient. Leadership must model appropriate behavior, and reporting channels must be genuinely accessible. Multiple reporting options matter when the alleged harasser holds a supervisory role, so that employees have a path to report that does not require going through the person they are reporting.

Remote and hybrid workplaces require explicit policy coverage. The 2025 CRD Guide confirms that harassment through electronic communication channels, including email, text, Slack, Teams, and video, carries the same obligations and investigation requirements as in-person conduct. An employee handbook written before your workforce went remote has a visible gap.

When harassment escalates to a formal agency charge, employers who have not established this preventive record face the EEOC and CRD at a significant disadvantage. Reviewing how to respond to an EEOC or CRD charge alongside your internal investigation procedures helps employers understand what the agency will look for in your response and how your investigation documentation will be evaluated.
