Dear Mr./Ms. Bossname,
I’m sorry to let you know in a letter rather than in-person, but since I’m not scheduled to be in the office for some time, I thought this was best. I am resigning.
I’ve secured another job, and they would like me to start as soon as possible. I’d be willing to stay on for two more weeks, in a remote capacity, if that would be helpful to the company.
I authorize my final paycheck to be direct-deposited into my account on file.
Thank you for the opportunity to work at XYZ Company.
