A Leave of Absence From Work Letter is a formal document informing your employer that you are taking a leave of absence from work. It should include the dates of your absence, an explanation of why you need to take the leave, and any other important information such as how long you plan to be away. The letter should also provide your contact details in case your employer needs to reach out to you during your absence. It’s important to present this information in a respectful and professional manner so that it may be taken seriously by your employer.
