Due to the current outbreak of communicable disease in our community, I must request a leave of absence.
I am at increased risk of infection and complications due to reduced immunity. Additionally, as you know, I have a newborn at home.
I've been working on Project A, and I'm confident that Nina is more than capable of taking that on. I'll be available by phone or email if she has any questions. (On a related note, I'd like to again urge you to reconsider your reluctance to allow our team to work remotely. I'm confident that with the appropriate technology, we can continue to work efficiently and even save the company money.)
I enjoy my work at ABC Company and look forward to returning to the team once the risk to myself and my family has passed.
