A written letter of resignation allows you the opportunity to leave your current employer with style. It's a perfect vehicle for controlling your message and preparing what you want to say.
In its simplest form, your resignation letter should include your name, company name, the addressee (your boss's name), notice of termination of employment, the effective date and your signature. Review sample letter.
If you are leaving on good terms and want to say a little more, be sure to only emphasize the positive. Perhaps you can thank your boss for the opportunities or experience he/she provided you. Review sample letter.
If, however, you are not leaving on good terms, be sure to abstain from blowing off steam. It is strongly advised to stay professional and refrain from including personal remarks in your resignation letter.
Communicating your differences can be accomplished in a separate vehicle. Remember, your resignation letter becomes a part of your personnel file. You don't want anything you write to reflect negatively on you in the future.
