Workplace Harassment Complaints: How to Write an Effective Letter

Understand Workplace Harassment

Workplace harassment refers to unwelcome behaviour that creates a hostile, offensive, or intimidating work environment. It can take many forms:

  • Verbal Harassment: Offensive jokes, insults, or inappropriate comments
  • Physical Harassment: Unwanted touching, physical intimidation, or threats
  • Sexual Harassment: Unwanted advances, gestures, or remarks
  • Discriminatory Harassment: Targeting based on race, religion, gender, disability, or age
  • Workplace Bullying: Exclusion, intimidation, or unfair treatment

Most countries have legal frameworks that protect employees from harassment:

  • United States: Title VII of the Civil Rights Act (EEOC)
  • United Kingdom: Equality Act 2010
  • Canada: Occupational Health and Safety Acts
  • Australia: Fair Work Act 2009

If you experience harassment, you have the legal right to report it internally (HR or management) or externally to labour authorities or legal representatives.

Gather Evidence Before Filing Your Complaint

Strong evidence helps HR or investigators handle your complaint effectively. Before submitting your letter, collect:

Dates, times, and locations of incidents
Names of all individuals involved, including witnesses
Screenshots, emails, text messages, or recordings (ensure they comply with privacy laws)
Copies of previous reports or communications about the issue

Organising your evidence will make your case clearer and help HR take timely action.

Keep Your Tone Professional and Factual

When writing your complaint:

  • Avoid aggressive or accusatory language
  • Do not include vague claims or emotional outbursts
  • Stay calm, factual, and specific
  • Clearly state what you expect as a resolution

A professional tone strengthens your credibility and helps HR address the issue effectively.

Tips for an Effective Workplace Harassment Complaint

Be Specific: Include names, dates, and detailed examples.
Remain Professional: Avoid emotional or accusatory wording.
Follow Policy: Submit the letter according to your company’s HR procedures.
Keep Copies: Retain a copy of your complaint and all correspondence.
Follow Up: If you do not receive a response within 14 days, send a polite follow-up or escalate to senior management.

What to Do If Your Complaint Is Ignored

If HR or management fails to act, you can escalate your complaint to:

  • Senior management or company directors
  • External authorities, such as the EEOC (U.S.), ACAS (UK), or local labour boards
  • A solicitor or employment lawyer, especially in cases of retaliation

You are legally protected against retaliation for making a genuine harassment complaint.

Frequently Asked Questions (FAQs)

1. Can I file an anonymous complaint?
Yes, some organisations allow this, but named complaints are usually taken more seriously and are easier to investigate.

2. How long does HR take to respond?
Typically within 7–14 days, though complex investigations may take longer.

3. Can I be fired for reporting harassment?
No. Retaliation is illegal. If you experience it, contact a legal adviser or employment tribunal.

4. Should I include evidence with my complaint?
Yes. Attach emails, messages, or witness statements to support your case.

5. What if HR does nothing?
Escalate to senior management, external authorities, or legal counsel if no action is taken.
