If you're pregnant and plan on quitting to raise your child, you can use this letter to resign from your current job.
As I am now several months into my pregnancy, I wish to devote my time to preparing our home and my life for my baby. Therefore, I am resigning from my position of telephone sanitizer as of Friday, July 13.
I will leave my current projects in as good shape as I can for my successor. I will be available via e-mail to answer questions if needed.
I have enjoyed working with (the company) and I wish everybody all the best.
