Warning Letter to Employee to Behave Politely

Reviewed & updated by Updated Originally published

A warning letter regarding impolite behavior is issued by an employer, manager, or HR representative to address an employee’s inappropriate conduct. It explains the concerns and requires the employee to communicate professionally with colleagues.

The tone should be firm, respectful, and factual. The letter must identify the conduct that prompted the warning, explain the improvements required, and state the possible consequences of further misconduct.

Sample Letter #1

To:
John Keith
Assistant, Stars Marketing Company
City Tower, 3rd Floor
Michigan, USA

April 17, 20XX

Subject: Final Warning Regarding Disrespectful Workplace Behavior

Dear John,

I am writing regarding your conduct on April 15, 20XX, when you shouted at a senior staff member in the presence of visitors and area managers. This incident was reported by your manager and follows an earlier warning about inappropriate conduct toward a colleague.

Shouting at colleagues is unacceptable and does not meet the company’s standards of professional behavior. It disrupts the working environment and can damage working relationships.

We value your contributions, but all employees are expected to treat others respectfully, regardless of their position or seniority. If you have a concern, raise it calmly with your immediate supervisor rather than confronting a colleague aggressively.

This letter serves as a final warning. You are required to communicate politely, manage disagreements professionally, and follow the company’s code of conduct. Further misconduct may result in disciplinary action, including termination, in accordance with company policy.

If you wish to respond to the concerns outlined in this letter, please contact [HR Representative] by [Date].

We expect immediate and sustained improvement in your behavior.

Yours sincerely,

Anderson
CEO, Stars Marketing Company

Sample Letter #2

To:
Robert
Assistant, Stars Marketing Company
City Tower, 3rd Floor
Michigan, USA

April 17, 20XX

Subject: Final Warning Regarding Disrespectful Workplace Behavior

Dear Robert,

This letter concerns your conduct during a colleague’s project presentation on [Date]. According to the report received from your branch, you interrupted the presentation, shouted at the presenter, and criticized his performance in front of other staff members.

Such conduct is unprofessional and undermines the respectful environment needed for colleagues to share ideas and learn from one another. Feedback should be communicated constructively, without shouting or personal criticism.

As previously communicated to staff, everyone is expected to maintain courteous and professional interactions. You are required to allow colleagues to speak, express disagreements respectfully, and raise concerns through the appropriate channels.

Please treat this letter as a final warning. Any further misconduct will be reviewed and may result in additional disciplinary action, including termination, in accordance with company policy.

You may provide a response or request clarification by contacting [Manager or HR Representative] at [Contact Details].

I expect immediate and lasting improvement in your behavior.

Yours sincerely,

Anderson
CEO, Stars Marketing Company
