Apology Letter for Absence from Work Due to Illness

An apology letter for absence from work due to illness informs your employer your inability to be at work due to sickness. You will write this letter if you were sick and you could not inform your boss you won’t make it to work.

Your employer doesn’t expect you to be away from your station without notifying them. If this occurs, writing a letter to explain the circumstances could be the best way to earn trust and forgiveness. In the letter, you must define the events that led to your absence.

How to Apologize at Work for Missing Work

Acknowledge your mistake

When writing an apology letter for being missing work, start by acknowledging your mistake. Your employer expects you to inform them if you are absent from work. Admit you violated company rules and ask for forgiveness.

Suggest how you will handle pending tasks

After a few days form your duty station, you will find work has piled on your desk. Depending on the urgency of the job at hand, you can commit more hours each day to complete the job. You can sacrifice your weekend to finish work.

Apologize immediately

You shouldn’t delay the apology, immediately you are back to work, write the letter and apologize to your boss. A prompt apology will help to calm the issue.

Don’t lay blame on others

When apologizing, avoid transferring responsibility to other parties. Avoid suggesting to your boss they should have called you to know where you were.

Consider meeting your boss in person

After writing the letter or email to apologize for being absent to work, it could be proper to visit your boss and apologize in person. You can also consider following up the email or letter to know if your employer requires any further information.

Dear Sir,

Kindly allow me to pass my apologies for being absent from work for 4 days from March 23, 2019, to March 26, 2019. The night before 23rd I woke up with severe back pain. I was rushed to Boston city Hospital and admitted for three days.

Because of my condition, I couldn’t contact you. I understand I have lots of pending tasks and will do all I can to finish the work.

I will get to work an hour earlier for this week until I complete all the pending work.

Once more I’m sorry for not contacting your office and thank you for your support.

Dear Sir,

I am writing to apologize for my being absent from the office for three days, from Tuesday, October [00/00/0000] to Thursday, October [00/00/0000]. I woke up with a serious headache, I really wanted to report to work but then I started feeling very weak and dizzy. I was taken to hospital for treatment and I had to be hospitalized for two days and that is why I did not manage to inform you on time. I understand that I have a lot of work pending but I assure you that I will complete it as soon as possible.

I apologize for any inconvenience I may have caused the office. If required, I am ready to work overtime and during the weekends to compensate for the time I was not in the office. I feel healthy now and I will be more productive at work.

I hope you will accept my sincere apology.

Yours Sincerely,
