A Leave of Absence Letter for Family Reasons is an official document providing the employee or employer with written notification that a family leave is being requested. The letter should include the amount of time requested, the date requested to commence the leave and a completed authorization form or other paperwork as applicable. It should also provide an explanation as to why the leave is needed, including any medical reason or extenuating circumstances. This letter serves to establish a clear understanding between both parties in order to ensure that all expectations are met.
