A resignation letter is a formal document submitted by an employee to officially inform their employer of their intention to leave the organization. It generally includes a clear statement of resignation, the proposed last working day, and optionally a brief reason for the departure. The letter may also express appreciation for the opportunities, support, and experiences received during the employee’s time with the company. Additionally, it often includes an offer to help during the transition period, such as training a replacement or completing pending tasks. Signed by the employee, it reflects professionalism and ensures a respectful and smooth exit process.
