How to Write an Effective Internal Complaint About Discrimination or Harassment
You have decided to report what is happening. The question now is how — what to include, what tone to use, how to frame it so that the complaint is taken seriously and creates a record that protects you regardless of the employer’s response.
An internal complaint is two things at once. It is a request for the employer to address unlawful conduct. It is also a document — a written record that establishes what the employee reported, when they reported it, and what they said. If the employer responds appropriately, the complaint has done its first job. If the employer retaliates, ignores the complaint, or conducts a sham investigation, the complaint becomes the foundation of a legal claim. It must be written to serve both functions.
What follows is practical guidance on how to write an internal complaint that is clear, credible, and legally effective.
Put it in writing
An oral complaint to a supervisor or HR representative is protected activity under FEHA, and it can trigger the employer’s obligation to investigate. But an oral complaint can be denied, minimized, or mischaracterized after the fact. “I don’t recall that conversation.” “She mentioned she was unhappy, but she didn’t say it was discrimination.” “He raised some concerns but never used the word ‘harassment.’”
A written complaint eliminates that ambiguity. It creates a fixed record with a date, a recipient, and specific content. It cannot be paraphrased into something less serious. It cannot be forgotten. It exists.
Send the complaint by email to the person or department responsible for receiving such complaints — typically HR, a compliance officer, or the individual identified in the employer’s anti-harassment policy. If you are unsure who to address it to, send it to HR and to your supervisor’s supervisor. Keep a copy in your personal records — forwarded to a personal email account at the time of sending.
What to include
An effective complaint is specific, factual, and organized. It does not need to be long. It does not need legal citations. It needs to tell the reader what happened, who did it, when it happened, and why the employee believes it is connected to a protected characteristic or protected activity.
Identify the conduct. Describe the specific actions, statements, or patterns that you are reporting. Use direct quotes where you remember them. Describe physical conduct precisely. Do not summarize — specify.
Not this: “My supervisor has been creating a hostile work environment.”
This: “On March 3, during a team meeting, [supervisor name] said, ‘[direct quote or close paraphrase].’ On March 10, [supervisor name] reassigned my largest client account to [colleague name] without explanation. On March 14, [supervisor name] told me in a one-on-one meeting that I ‘might be happier somewhere else.’ These incidents began after I disclosed my pregnancy on February 25.”
Identify the people involved. Name the person or people whose conduct you are reporting. Name any witnesses who were present. If you are aware of other employees who have experienced similar treatment, you may note that, though you are not required to.
Identify the timing. Include specific dates wherever possible. If exact dates are unavailable, provide approximate dates with enough context to locate them (“the week of March 3” or “the Monday after the all-hands meeting”). The chronology matters — particularly the relationship between the protected event (your complaint, your disclosure, your leave request) and the adverse conduct that followed.
Connect the conduct to a protected characteristic or activity. The complaint should make clear why you believe the conduct is discriminatory, harassing, or retaliatory. You do not need to cite statutes. You do not need to use legal terminology. But the complaint should identify the protected characteristic (race, sex, age, disability, pregnancy, etc.) or the protected activity (filing a prior complaint, requesting accommodation, taking leave) that you believe motivated the conduct.
“I believe these actions are related to my pregnancy, which I disclosed on February 25. The change in my supervisor’s treatment of me began immediately after the disclosure.”
“I believe I am being retaliated against for my complaint to HR on January 15 about [supervisor]’s comments about my race.”
This sentence — connecting the conduct to the protected basis — is the most important sentence in the complaint. Without it, the employer may treat the complaint as a general workplace grievance rather than a report of unlawful conduct. With it, the employer’s obligation to investigate is triggered, and the employee’s protected-activity status is established.
What tone to use
Write the complaint in a calm, professional, factual tone. You are not writing a legal brief or an emotional appeal. You are creating a record.
Avoid: accusations of motive that you cannot prove (“my supervisor is a racist”), inflammatory language (“this company is a cesspool of discrimination”), threats (“if this isn’t fixed I will sue”), and ultimatums (“I demand that [supervisor] be fired immediately”).
Instead: state the facts, identify the pattern, connect it to the protected basis, and request a response. The complaint should read like a report from a credible, composed professional — because that is what it is, and that is how it will be evaluated if it later becomes evidence.
What to request
End the complaint with a clear statement of what you are asking the employer to do. Common requests include:
“I am requesting that the company investigate this matter and take appropriate corrective action.”
“I am requesting that the company address the conduct described above and ensure that it does not continue.”
“I am requesting a meeting with HR to discuss these concerns and to explore what steps can be taken to address them.”
You are not required to propose a specific remedy. You are required to make clear that you are reporting conduct you believe is unlawful and that you expect the employer to respond.
What happens after you submit it
The employer is obligated to investigate. The investigation should be prompt, thorough, and impartial. You should expect to be interviewed by the investigator and asked to provide additional details. You should cooperate fully and honestly.
You are protected against retaliation from the moment you submit the complaint. Any adverse action taken against you after the complaint — termination, demotion, reassignment, negative performance evaluation, exclusion from opportunities — may constitute retaliation, and the temporal proximity between the complaint and the adverse action is evidence of the connection.
If the employer does not respond, does not investigate, or retaliates against you, the written complaint becomes the centerpiece of a retaliation claim. It establishes that you engaged in protected activity, that the employer was on notice, and that the employer’s subsequent conduct was a response to the complaint.
One final point
You do not need to wait until you are certain that the conduct is illegal to file an internal complaint. You need a good-faith, reasonable belief that the conduct you are experiencing is connected to a protected characteristic or activity. If you are wrong — if the conduct, on investigation, turns out not to be unlawful — you are still protected against retaliation for having made the complaint in good faith.
The purpose of the complaint is not to adjudicate the claim. It is to put the employer on notice, to trigger the investigation, and to create a record. The legal analysis comes later. The complaint comes now.
If you are experiencing conduct at work that you believe is discriminatory, harassing, or retaliatory, putting it in writing — specifically, factually, and calmly — creates a record that protects you regardless of how the employer responds. The complaint is the first official step, and it should be taken deliberately.
