If you need to request for leave due to personal reasons that are confidential, here’s a template you can use to write a leave of absence letter for personal reasons.
I’d like to formally request for a leave of absence from [date] to [date] due to personal reasons, which I want to remain confidential.
I hope for your understanding on this matter. I need to urgently address my personal concerns so that they would not interfere with my work and long-term success in this company.
