What Is an HR Complaint?
An HR complaint is a formal complaint submitted to an employer’s human resources department reporting workplace issues that may violate company policy or the law. HR complaints are most appropriate when the issue involves more than a routine disagreement and may require investigation or corrective action.
Common reasons employees file HR complaints include:
- Discriminacion based on a protected characteristic such as gender, race, disability, sexual orientation, national origin, medical condition, or gender identity
- Hostigamiento o Acoso, including sexual harassment or a hostile work environment
- Wage violations, such as unpaid overtime or missed meal breaks
- Represalias after engaging in protected activity, such as reporting misconduct or unsafe working conditions
Submitting a written HR complaint helps establish a clear record of what happened and when, which can be critical evidence if a dispute later arises.
How to Write a Complaint Letter to HR (Step by Step)
Writing a strong formal complaint letter requires clarity, professionalism, and attention to detail. Whether you submit your complaint by email or form, the goal is to document facts, not emotions.
Step 1: Use a Clear Subject Line
Example:
Formal Complaint – Discrimination Based on Disability – [Your Job Title] – [Date]
Step 2: Summarize the Issue Clearly
In the opening paragraph, explain what happened, who was involved, and why the conduct may violate the law or company policy. Focus on facts rather than opinions.
Step 3: Include a Timeline With Specific Dates
List incidents in chronological order, including:
- Dates and times
- Names and job titles of involved individuals
- Names of witnesses, if any
Specific dates and details strengthen credibility and help HR investigate.
Step 4: Attach Supporting Evidence
Attach critical evidence such as emails, text messages, performance reviews, or other documents. Keep copies for your own records.
Step 5: Respectfully Request Action
State what you are asking HR to do, such as conduct an investigation, address inappropriate behavior, or take corrective action.
Tip: Avoid emotive language. Stick to objective descriptions of what happened.
HR Complaint Form vs. Email
Some companies require employees to use a complaint form, while others accept complaints by email. Either option can be effective as long as it creates a paper trail.
- Complaint forms help standardize reporting
- Emails allow more detail and attachments
Always save copies outside of your work system.

Dos and Don’ts When Writing HR Complaints
What to Do
- Use clear, factual language

- Reference company policy or protected characteristics when relevant
- Keep your own records of everything submitted
What to Avoid
- Threatening legal action in the complaint

- Relying only on verbal conversations
What If HR Doesn’t Respond?
If HR does not respond within a reasonable timeframe:
- Send a polite follow-up referencing your original complaint
