Sub: Complaint Against Supervisor

Dear Ms. Dorothy,

I am writing this letter to bring to your notice the behavior of one of the supervisors, Mr. Adam Smith.

From last couple of months, I have experienced that Mr. Adam uses abusive language. Especially on October 13, 2025, he was found using extremely foul language with me.

The purpose of writing this letter to you is to please find out the issue he has so that the problems can be solved and these kinds of episodes are not repeated in future.

I have been associated with this company from last eight years and I have thoroughly enjoyed working here. I understand that you value your employees and treat them with dignity and respect but this kind of behavior is something that is not appreciated.

Looking forward for your response on this.

Sincerely,

Amanda Smith
