Apology Letter For Unplanned Absence

To [Name],

I am writing this letter to express my sincere apologies for my unplanned absence. I understand that this was an inconvenience to you and the team and I am truly sorry for any disruption this caused.

I understand that I should have notified you of my absence in advance, and for that I apologize. I realize that I have let you down and I am deeply sorry for any trouble this caused.

I can assure you that this was an isolated incident and it will not happen again. I take my role seriously and I am committed to meeting all my obligations. I understand that this is not the kind of behavior that is expected of me and I will do my best to make sure it does not happen again.

I understand that I have to make up for the time I missed and I am willing to put in extra hours if needed. I am also willing to take on additional tasks or responsibilities to make up for the time I missed.

Once again, I apologize for my unplanned absence and I understand that it was unacceptable. I will do my best to make sure this does not happen again and I will do whatever it takes to make up for the time I missed.

Sincerely,

[Your Name]
