Subject: Temporary Absence Due to Family Illness

Dear [Boss's Name],

I am writing to inform you that I will need to take a temporary leave of absence from work due to a family member's illness. As you are aware, my family's health and well-being are very important to me, and I must be with them during this difficult time.

I will be away from work for [number of days/weeks], and I will make sure to communicate with [coworker's name] to ensure that all of my work is being taken care of in my absence. Please let me know if there is anything else you need from me during this time.

Thank you in advance for your understanding and support during this difficult time.

Sincerely,
[Your Name]
