Sample Apology Letter to Boss for Mistake

To err is human. Spending the major part of our days in an office, making mistakes is common. While erring too often is a sign of carelessness, an odd mistake at the workplace is usually taken with a pinch of salt. But even if your boss is not too upset with you, it is your duty to apologize to him if you have made a mistake at work.

So how does one do this? Verbal apologies may seem insincere. If you really want to reach out to your boss and make him believe that you did not deliberately do something wrong, you have to sound sincere. And you can do so by writing a well-crafted apology letter to him or her and explain why you made the mistake, how you intend to make amends for it and what measures you have taken so that it is not repeated in the future.

It does not matter if you work in the same office as your boss – send him an apology letter. Admit that you have made a mistake. Let him know that you are honest about your work and will do all that you can for your workplace. To look at a sample apology letter, refer below:

Mr. Allen Lessard
Marketing Manager
6182 Cherry Road
Seward, NE 71635


Dear Mr. Lessard:

I am completely mortified at the circumstances that transpired at the annual marketing meeting yesterday. And all due to my inability to provide you with the correct figures for the presentation. I appreciate the fact that you handled the situation without any repercussions but I realize that the situation could very easily have gone haywire.

While researching information about Mattel’s competition in the market, I came across a figure which explained the downfall of a particular competitor in the wake of our company’s success. I isolated this information but forgot to tag it and ended up erroneously placing it on the presentation that I was creating. It was a terrible oversight and I realize that it could have cost the company its reputation.

Please rest assured that I will be careful about details such as these in the future. I apologize for the inconvenience (and embarrassment) that it caused you. Working for Mattel is the best thing that has happened to my career and I wouldn’t jeopardize it knowingly.

Thank you for not pointing out the fact that the mistake was actually mine. I honestly appreciate this gesture.



Charles Perez
Marketing Officer
