write apology letter to copmay for not attending company annual function. You should mention why you were not attended, what you done for that, what you will do to compensate it.

Dear Sir/MadamI am writing this letter to request you please accept my very sincere apology due to unavailability of myself on company's annual meet. In more detail, because of some unforseen health issue of my grand mother I needed to visit the hospital. Because of her chronic situation I addmitted her in ICU. Unfortunertly, I am the only one for responsible for her to lookafter. Hence, I was not able to address an important yearly function of our company. Having said that, on same day I was informed to my other colleague of marketing tream for unavailability and also handed over powerpoint presentation to them with copy mark to head of department via mail. To compensate my absence of meeting and being a responsible employee I would like to work for extra hours to not only full fill my role and responsibility but also to achieve given goal by higher management as decided for me on that annual meeting. Furthermore, with this letter I also attched my work agenda for the following month. I hope you understand my medical emergency and looking forward to your acceptance of my heartfelt apology. Yours faithfully, Anushree Raval.
