Dear Mr./Ms. Manager:

Please accept this letter as my notice of resignation, effective (date).

This was not an easy decision to make. I am grateful for the rewarding employment I’ve had with (company name). After much consideration, though, I have accepted a position with another company.

Sincerely,

(Your Signature)
