I hope this letter finds you well. I am writing to formally request a leave of absence from my position at Gracefield University. I would like to take this opportunity to explain the reason for my request and provide appropriate arrangements for the duration of my absence.
I need immediate leave from March 10 to March 20, 2050, to care for my seriously ill elderly mother in another state. I've organized my responsibilities, identified colleagues to cover my duties, and will be available via email and phone for urgent matters. Your understanding and support are appreciated.
Thank you for your understanding and support during this challenging time. If you have any questions about my request, I'm happy to discuss it further. I appreciate your consideration and believe my temporary absence will benefit both my family and my future contributions to Gracefield University. Thank you for your attention; I look forward to your positive response.
