Sub: Complaint Letter Against Co-worker

Dear Sir,

I would like to report a conflict between me and the (Co-worker person name) working in the (department name). There have been several incidents over the last few days, and I feel that it is time to report a formal complaint against him/her. (Describe in your own words).

I would like to report the occurrences on record as follows:

On [Date], the aforementioned coworker and I had an argument over his habit of passing comments against me and a few other coworkers. He has been doing it frequently, and no one confronts him for that. But after tolerating him for several days, I confronted him saying that whatever he did was unethical and not acceptable at cost. (Describe your actual cause and situation). But despite that, he continues to do so, and now the time has come that you take cognizance of his behavior and enforce strict action.

His wrongdoings are not confined to that, he also has a bad habit of going into other people’s cabin, using their belongings, stealing things, and also using their personal computers. As I feel that I am a loyal and hardworking employee, I feel concerned about the situation as it affects me as well as others due to the ordeal created by that person. (Explain all about the situation). It has affected many in the past and has caused tremendous trouble to exist and has made my work almost impossible. (Cordially describe your requirement). I would like to resolve this issue as soon as possible and request you to understand my situation and take appropriate action.
