Warning Letter for Fight with Coworker

When an employee’s behavior is not acceptable in the organization, the employer issues a warning letter to the employee.

There are many situations when an employee’s relationship becomes unpleasant with co-workers. Sometimes, that unpleasant relationship results in such acts on the part of the employee, which disregards the job duties and responsibilities of the employee. The employee’s productivity is also reduced when he or she cannot work peacefully with fellow workers.

Sometimes, the misconduct of an employee with co-workers is not very significant. It causes no serious damage to the interests of the employee. In such a case, terminating the employee’s job is not recommended. Many organizations write a warning letter in such a situation so that these kinds of things can be avoided in the future.

Every employee is responsible for maintaining a peaceful environment in the company. However, some employees do not maintain a good relationship with co-workers for many reasons. The warning letter by the employer will alert the employee and he will try to avoid any conflict in the future.

The letter should start with the statement that the employee’s misconduct has become unacceptable and this situation is occurring repeatedly despite multiple verbal warnings.

Moreover, the letter should also specify in the letter that the employee should treat it as a warning from the employer. End the letter with the expectation that the employee will behave well hereafter.

Sample Letters:


We are writing to address an unpleasant incident that took place within the workplace on Thursday, 22nd of March. The management is utterly dismayed that you got into a fight with your teammate, XYZ during your project meeting. This behavior is completely unacceptable.

Let us remind you that our company encourages professionalism. All disagreements must be resolved professionally instead of resorting to fights and discord. This disrupts our work environment and leads to long-term resentment among colleagues. When our employees do not work together in harmony, it affects the overall productivity.

Moreover, disrespectful and hostile behavior towards coworkers goes against the company’s policies. We value an amicable collaboration that leads towards the company’s goals.

We, therefore, urge you to adopt a more respectful behavior towards all of your colleagues in the future. Resolve disagreements professionally. You may involve the management in case of a serious discord instead of resorting to a fight.

Please take this warning letter seriously and avoid unprofessionalism in the future.


We are writing in response to reports received against you and XYZ about a fight that took place within the office premises yesterday. This behavior goes against our policies and is highly discouraged.

The management is, therefore, suspending you and XYZ for three days as a disciplinary action. During this time, we urge you to reflect on your behavior and its consequences. You must resolve all future conflicts and disagreements in a professional and civilized manner.
