A leave application for a mother’s illness is a formal request to an employer for time off to care for an ailing parent. It should be professional, concise, and include essential details such as the reason for leave, the expected duration, and any supporting documents, like a medical certificate. For example: “Dear [Manager’s Name], I am writing to request leave from [start date] to [end date] due to my mother’s illness. She has been diagnosed with [condition] and requires my care during this time. I have attached a medical certificate for your reference. I will ensure my responsibilities are delegated before my leave begins. Thank you for your understanding and support.” This approach demonstrates professionalism while emphasizing the urgency of the situation. Employers typically appreciate clear communication and proper documentation, making it easier to approve such requests.
