Dear [Manager's Name],
Please accept this letter as notice that I am resigning from my role as [Your Job Title] at [Company Name]. My last working day will be [Last Working Day].
My family needs me at home at the moment: [a parent's health / caring responsibilities] mean I have to be available in a way this role doesn't allow, so I've made the difficult decision to resign.
If there's an option I haven't considered, such as a period of unpaid leave or reduced hours, I'd be glad to talk about it. If not, I'll use my notice period to hand over my work fully and make sure the team has everything it needs.
Thank you for your understanding, and for the support you've given me at [Company Name]. I hope to return to work when things settle, and I'd like to stay in touch.
Sincerely,
[Your Name]
