Don’t be Afraid to Complain, Harassment in the Workplace is Unlawful

If you have experienced inappropriate conduct at work and are ready to report it, how you document that complaint matters. A well-written sexual harassment complaint letter template creates a paper trail, puts your employer on legal notice, and becomes critical evidence if litigation follows.

This page covers what to include, what to avoid, and what California law requires of your employer once that letter is submitted.

Why Your Complaint Letter Matters Under California Law

Under California law, employers are not just encouraged to address harassment complaints. They are required to. Cal. Code Regs. tit. 2, § 11023 mandates that every employer maintain a written harassment, discrimination, and retaliation policy that includes a formal complaint process. That process must:

  • Provide employees with a way to report harassment without going directly to the harasser
  • Designate a confidential complaint mechanism
  • Require that all complaints be investigated promptly
 

What this means for you: submitting a formal written complaint activates a legal obligation your employer cannot ignore. If they fail to investigate promptly or take corrective action, that failure becomes part of their liability exposure.

Employers who receive notice of harassment and do nothing, or who retaliate against the employee who reported, can face significant legal consequences under the Fair Employment and Housing Act (FEHA). The moment you put your complaint in writing, the legal clock starts ticking.

What to Include in your Sexual Harassment Complaint

A complete sexual harassment complaint letter template should cover each of the following clearly and in plain language. Whether you’re drafting from scratch or adapting a complaint letter sexual harassment example you found online, these elements are essential.

Your identifying information. Your full name, job title, department, and direct supervisor’s name.

Who the harasser is. Their name, title, and relationship to you: supervisor, coworker, client, or contractor. Employer liability standards differ depending on whether the harasser held authority over you.

A specific description of each incident. List incidents separately with the date, time, location, and exactly what happened. Courts and investigators look for specificity. The more detail you include, the harder the complaint is to dismiss.

How the conduct affected you. Describe the impact on your ability to work and your environment. This is directly relevant to establishing a hostile work environment claim under FEHA.

Whether you previously reported it. If you reported the harassment before and no action was taken, say so with dates and names. Prior reporting with no response strengthens your position.

 

What you are requesting. A formal investigation, corrective action, protection from retaliation, and confidentiality to the extent possible.

Sexual Harassment Complaint Letter Template

Below is a sample letter you can adapt. Replace all bracketed fields with your specific information. Keep a copy of everything you send:

Dear [Human Resources Representative],

I am writing to report that I have been subjected to sexual harassment in the workplace, which is prohibited by California law. The harassment has created a hostile work environment, and I feel that it is important to bring this matter to your attention.

Specifically, [describe the behavior or incidents that constitute the harassment, including dates, times, and any witnesses]. This behavior has created an uncomfortable and intimidating environment for me and has interfered with my ability to do my job effectively.

I am requesting that an immediate and thorough investigation be conducted into this matter, in accordance with California law. I also request that appropriate action be taken to put a stop to the harassment and prevent it from happening in the future.

As you know, California law prohibits retaliation against an employee who reports sexual harassment. Therefore, I request that you take all necessary steps to protect me from any retaliation or adverse action for reporting this matter.

Please keep the matter confidential to the extent possible to protect my privacy and prevent retaliation.

Thank you for your prompt attention to this matter.

Sincerely,

[Your name]

What Happens After You Submit Your Complaint

Once your employer receives a formal complaint, California law, including the standards codified in Cal. Code Regs. tit. 2, § 11023, requires them to investigate promptly and take remedial action if harassment is confirmed.

Investigation. HR or a designated investigator should contact you to gather information. You have the right to participate fully and name witnesses.

Timeline. There is no fixed statutory deadline, but “prompt” is the legal standard. Unreasonable delays can themselves be evidence of employer failure.

Outcome. You should receive notice of the investigation’s conclusion. Confirmed conduct may result in corrective action up to and including termination of the harasser.

Protection from retaliation. Any adverse employment action after you file, including termination, demotion, or schedule changes, may constitute unlawful retaliation. For a detailed breakdown of what that looks like, see our post on what is considered retaliation at work.

If your employer fails to investigate or retaliates against you, you have legal options beyond the internal process.

How to Write an HR Complaint: Mistakes to Avoid

Knowing how to write an HR complaint means knowing what to leave out as much as what to include. Common mistakes that can weaken your complaint:

Vague descriptions. “He made me uncomfortable” is not enough. Describe specifically what was said or done and when. General statements give investigators less to work with.

Emotional conclusions instead of facts. Describe what happened and let the record speak. Stick to documented events rather than characterizing the harasser or predicting bad faith from HR.

Submitting only verbally. Always follow up any verbal report in writing. Without a paper trail, it is much harder to prove you reported it.

Waiting too long. Under FEHA, you generally have three years from the most recent violation to file a complaint with the California Civil Rights Department. The sooner you report, the stronger your record.

Your External Options Beyond the Internal Process

Submitting an internal complaint is not your only path. In California, you can also file with:

The California Civil Rights Department (CRD) (formerly the DFEH), which enforces FEHA. File online at calcivilrights.ca.gov. A CRD complaint is required before you can bring a civil lawsuit in California under FEHA.

The Equal Employment Opportunity Commission (EEOC), which enforces Title VII at the federal level. File at eeoc.gov.

Filing with an agency and filing a civil lawsuit are different processes with different timelines. An employment attorney can help you determine which filings apply and ensure you do not miss any deadlines.

Frequently Asked Questions

Do I have to use a specific format? No. There is no legally mandated format in California. What matters is that your complaint is in writing, specific, and directed to the right person, typically HR or the compliance officer named in your employer’s anti-harassment policy.

Can I be fired for filing a complaint? Terminating or retaliating against an employee for reporting harassment is unlawful under both FEHA and Title VII. Filing a sexual harassment complaint letter is a protected activity under California law. If retaliation follows, document it immediately and speak with an employment attorney.

Will my letter become public? Not automatically. Employers are required to keep investigations reasonably confidential. If litigation follows, the letter may become part of the legal record.

What if my company has no HR department? Direct your complaint to an owner, senior manager, or another company contact in writing. If you believe no internal process will be taken seriously, speak with an employment attorney before or alongside your internal complaint.
