This printable resignation letter cites bad vacation policies as the reason for quitting.
This letter serves as my resignation, effective (date). I'm sorry to have to leave (Company), as I have learned a lot and grown in many ways here.
Unfortunately, vacation policies simply don't line up with the health and travel needs that my family requires. It's important for me to prioritize my children as much as I can. I can work until my date of departure, and I'm happy to help train my replacement.
Thank you for all your support and understanding over the last (amount of time).
