If you're resigning from your position, it’s proper form to write a short resignation letter for submission to your supervisor and human resources department that makes your intentions official, regardless of how much notice you're able to provide. If you have time, type your letter in a word processing program.
Open a new document in your word processing software. Write the date at the top of the page. Address your letter to your supervisor or human resources administrator, or, if necessary, “To Whom It May Concern.”
Write this or something similar: “This letter serves as official notice of my resignation of my position, effective as of (insert date)."
Include additional information if desired, such as your reason for leaving or your contact information.
Sign your letter with a positive closing statement, regardless of what the final situation is with your employer. An example might be a single sentence, such as "It has been a pleasure working with you." You don't want to leave your position on a negative note if at all possible.
Provide a copy of the letter to your supervisor and the human resources manager. If that's not possible, just one copy to your supervisor is fine. Keep another copy for your records.
