How to Write a Work Complaint Letter

1. Why Write a Work Complaint Letter?

A formal work complaint letter is necessary when workplace issues remain unresolved despite informal discussions. A well-written letter helps:

Document workplace grievances for HR or legal purposes.
Ensure fair treatment and accountability.
Request corrective action or an investigation.
Prevent retaliation by maintaining an official record.

A complaint letter should be professional, factual, and solution-focused to increase the chances of a positive resolution.

2. When Should You File a Work Complaint Letter?

You should write a complaint letter if you experience:

Harassment, discrimination, or bullying from colleagues or managers.
Unfair treatment, favoritism, or wrongful termination.
Unsafe working conditions or labor law violations.
Wage disputes, unpaid overtime, or contract breaches.
Retaliation for reporting unethical behavior.

If the issue is serious (e.g., sexual harassment, workplace violence), report it immediately to HR or legal authorities before submitting a formal letter.

3. Where to Send Your Work Complaint Letter?

Your complaint should be directed to:

HR Department – For general workplace grievances.
Immediate Supervisor or Manager – If the issue involves colleagues.
Company’s Ethics or Compliance Office – For legal or ethical violations.
Labor Board or Legal Authorities – If HR fails to take action.

Find the HR department’s email, office address, or complaint portal in your employee handbook or company website.
