A medical leave letter is an official document requesting your employer to grant you a period of absence for medical reasons. This formal request should include information about the illness or injury and a description of the treatment that will be necessary. The letter may also include an estimate of how long you expect to be off from work. Remember, it’s important to provide enough detail in the letter so your employer can understand the situation and make an informed decision. By writing a thoughtful medical leave letter, you can help ensure your time away is respected and your job protected.
