Apology Letter to Boss for Mistake

An apology letter to the boss for a mistake is a letter written by an employee, who has committed a mistake and wants to apologize for it. It is addressed to the employer or the manager/boss and may increase the chances of the employer’s overlooking and forgiving of the mistake and saving the employee from any serious actions that might be taken by the employer.

Employees often make mistakes, which are either intentional or unintentional. Some of the examples of mistakes are:

  • Unprofessional behavior.
  • Immature behavior.
  • Miscommunication.
  • Submitting the wrong documentation.

Whether the employee intended to commit a mistake or not, it is always courteous and essential to apologize. In addition to a verbal apology, a written apology letter is always recommended for employees, as this makes a good impression on the employer.

Mainly, the effects of the mistake on the boss and the organization determine the information be included in an apology letter to the boss for a mistake. Usually, the following details are included:

  • Date.
  • Employee information.
  • Employer information.
  • Details of the mistake.
  • Explanation and reasoning, if possible.
  • Realization of the mistake.
  • Indicate remorse.
  • Apologize and seek forgiveness.
  • Ensure improvement.
  • Salutation and signature.

As this letter from the employee is kept by the manager as a record, if the employee makes a similar mistake again, the manager can use this apology letter as a reference to punish him or escalate the employee’s case to the upper management by stating that the employee has already done the same sort of mistake in the past and has repeated it now even after apologizing for it.


Sample Apology Letter to Boss for Mistake




Dear Ms. Sarah,

I am writing this letter to apologize for the mistake of sending the wrong XYZ project report to you and the client on 5th October 2019.

I was working on the night of 5th on that report. I wanted to make it perfect, so I did not sleep for the whole night. When I completed the report and composed an email to send it to you and the client, I attached the wrong file and sent the incomplete report with many mistakes. As I was sleep-deprived, I could not come the next morning and my phone battery died as well, which is why you could not approach me.

I am aware that you had to go through a lot of embarrassment in front of the client because of that wrong document, and the client meeting on the morning of 5th went in vain as well, wasting time and resources. I am extremely sorry, as I am the responsible person behind this.

I have arranged a new meeting with the client, in which I will explain all of this and apologize to him.

I hope you will understand and consider it a pure human mistake. Please, accept my apology.


John Dsouza.
