How Do I Apologize to My Boss for Missing Work Due to Health Issues?

I couldn't attend my duties for the past two weeks due to health issues. I couldn't communicate this to my boss in detail. I want to write a letter asking him to understand and forgive me for this delay and assure him about my performance in the future.

I understand from the message that you may have informed your boss over the phone, but it appears that you were unable to fully persuade him/her. Now, you can proceed to write an email and express your concerns:

Subject: Health Issues

Dear Sir/Madam,

Respectfully, I have been dealing with health issues for the past two weeks, as previously mentioned to you. Unfortunately, I was unable to convey this information via email due to certain circumstances.

Furthermore, I have attached my medical reference slips and bills, which indicate that I have been hospitalized or on medical rest based on doctors' recommendations during this period.

I acknowledge my mistake in not notifying you via email promptly, and I sincerely apologize for this oversight.

I kindly request your understanding and forgiveness for this error. I assure you that I will take necessary steps to ensure such oversights do not occur in the future and demonstrate my commitment as a valuable and productive member of the organization.

Thank you for your attention and consideration.

Best regards

Overall, your draft is okay, but a slight revision is required. It is as below:

a) The very first sentence is compound. Split it into two small sentences.

b) We do not know whether Narotham was hospitalized. Therefore, it is enough if we write, "I have attached a certificate from the doctors stating I was under medication."

c) In the third paragraph, it is enough if we write, "I regret my inability to intimate you through written communication." By the way, is it mandatory to provide written communication despite sickness?

d) In the last paragraph, it is not "condole" but "condone." Secondly, if the sickness was genuine, then the wording of this paragraph is too submissive. It is enough if we write, "In view of the above, I request you regularize my absence by granting me sick/earned leave. I will perform my duties to the best of my capacities once I attain complete medical fitness."
