1. Understand the Purpose of a Complaint Letter to Your Boss About Another Employee
A formal complaint letter to your boss is a professional way to report another employee’s behavior that negatively impacts you, your work environment, or company operations. Common reasons for filing a complaint include:
- Unprofessional behavior (rudeness, refusal to cooperate, gossiping, etc.)
- Workplace bullying or harassment
- Discrimination (gender, race, age, disability, etc.)
- Violations of company policies
- Failure to complete tasks or poor performance affecting teamwork
- Unethical or dishonest behavior (theft, lying, misuse of company resources, etc.)
A well-written complaint ensures your concerns are documented and taken seriously by your boss or HR department.
2. Identify the Correct Recipient
Before writing, determine where to send your complaint:
- Your immediate supervisor or manager – If the issue is minor and can be resolved internally.
- The Human Resources (HR) department – If the issue involves harassment, discrimination, or policy violations.
- A senior manager or director – If your boss is unavailable or involved in the issue.
Check your company’s employee handbook for complaint policies and procedures.
3. Gather Important Information Before Writing
Before drafting your letter, collect key details:
- The employee’s full name and job title
- Date, time, and location of incidents
- Names of witnesses (if applicable)
- Company policies that were violated
- Previous complaints or discussions regarding the issue
- Supporting evidence (emails, messages, reports, etc.)
4. Maintain a Professional and Respectful Tone
Even if you are frustrated, your letter should be polite, factual, and professional. Avoid personal attacks, emotional language, or threats, as a well-structured complaint is more likely to be taken seriously.
🚫 Instead of: “My coworker is completely incompetent and lazy!”
✅ Say: “I have concerns about my coworker’s lack of teamwork, which is affecting our project deadlines.”
🚫 Avoid ultimatums:
❌ “If you don’t fire them, I’m quitting!”
✅ Instead, say: “I hope we can find a resolution that allows for a more productive work environment.”
5. Start With a Clear Opening Statement
Begin with a direct statement explaining your complaint. Example:
“I am writing to formally report ongoing workplace issues involving [Employee’s Name]. Their behavior has created challenges in my work environment, and I would like to bring this matter to your attention for resolution.”
6. Describe the Issue in Detail
Explain the problem clearly and concisely:
- What happened?
- When and where did it occur?
- How has it affected you, your work, or the company?
- Have you attempted to resolve it informally?
Example:
“Since [Date], I have had ongoing difficulties working with [Employee’s Name]. They have repeatedly failed to complete assigned tasks on time, leading to missed deadlines and additional workload for the rest of the team. I have spoken with them privately on [Date] to address the issue, but no improvement has been made.”
7. Provide Supporting Evidence
Attach relevant documents, such as:
- Emails or chat messages from the employee
- Performance reports or project delays caused by the issue
- Witness statements from colleagues
- Copies of previous complaints or HR reports
8. Specify Your Desired Resolution
Clearly state what action you expect from your boss. Possible resolutions include:
- A formal discussion or warning given to the employee
- Conflict resolution or mediation
- Additional training for the employee
- A departmental change if the conflict is severe
Example:
“I kindly request that management address this matter with [Employee’s Name] and take the necessary steps to improve the situation. If possible, I would appreciate mediation or guidance on how to move forward.”
9. Request a Response and Set a Deadline
Give your boss a reasonable timeframe (e.g., 7-14 days) to respond. Example:
“I would appreciate a response within 10 business days outlining how this matter will be addressed.”
10. Include Your Contact Information
Ensure your boss can reach you by providing:
- Full name
- Job title and department
- Company email and phone number
11. End With a Professional Closing Statement
Thank your boss for their time and cooperation. Example:
“Thank you for reviewing my complaint. I appreciate your time and look forward to your response.”
