A resignation letter notifies an employer that an employee is leaving their job. It provides written notice of the resignation including the last date of employment. The letter should state the reason for resigning, make clear the definite resignation date at least two weeks in the future, and include a note of appreciation or regret. The letter should be brief, positive, focused on the fact of leaving and resignation date without criticizing management or the job. A template and example resignation letter are also provided.
