A resignation letter is an official, formal communication that an employee submits to their employer to announce their decision to resign from their current position within the company. This document serves as an important step in the employee’s transition and is typically written in a respectful, professional tone. The letter usually begins by clearly stating the intention to resign, often specifying the position held, and providing the employer with the intended last working day. In some cases, the employee may include a brief explanation for their resignation, although this is optional and varies depending on the individual’s situation. Reasons could include career advancement, personal commitments, health reasons, or a desire for a new challenge, but the level of detail provided is up to the employee’s discretion.
