A Leave of Absence Letter to Employer is an official document from an employee requesting permission to take time off from their job. The employee must include clear and accurate reasons for taking a leave of absence, such as family emergency or medical leave, and must request a specific length of time. This letter should also be accompanied by any necessary supporting documentation, such as a doctor’s note. Since this is a formal business document, it should be written in a professional and courteous tone and provide sufficient detail regarding the request.
