A Last Day Worked Letter is a formal document used for tracking or validating the last day of employment for an individual. It’s typically issued by the employer as a written confirmation of an employee’s termination or resignation from their position. This letter serves to confirm both legal and financial liabilities that may exist, such as when and how final wages should be paid or for the purposes of verifying sources of income for tax filing or unemployment insurance claims. Creating a Last Day Worked Letter is an essential part of completing any personnel transition process.
