A resignation letter is a formal document that an employee submits to their employer to officially communicate their decision to leave the organization. This letter generally outlines the employee’s intent to resign, specifies their final working day, and may optionally include a brief explanation for their departure. In many cases, the letter also expresses appreciation for the opportunities and experiences gained during their tenure. It may further offer assistance in ensuring a smooth transition, such as training a replacement. Signed by the employee, this letter reflects professionalism and respect, providing appropriate notice to the employer.
