Whether the infraction was intentional or not, acknowledging your error and apologizing for it shows the recipient that you can be trusted even if the mistake made suggested otherwise.

Some work mistakes are more serious than others, some even have financial repercussions, but taking the time to craft a sincere apology letter will help in making things right again, and improve your chances of being forgiven.

Take for example, medical apologies, where a mistake or error can have extremely serious consequences. Research has shown that doctors aren't typically sued for malpractice because they made a mistake, they're sued because they shirk responsibility, fail to apologize and/or refuse to offer fair compensation.

An apology letter for a mistake is simply a means of acknowledging that an error was made, usually in business and at work, and needs to convey that you understand that it was your fault and that you are honorable enough to apologize for it.
