How do I write a leave application for urgent work?
Address the principal, class teacher or manager, state that you have an urgent piece of work at home on the given date, and request leave for that day.
Is "urgent piece of work" a valid reason?
For a day or two, yes. For longer leave, give a clearer reason so the request is not sent back.
Can a parent write this application for a child?
Yes. For school students a parent can sign the same letter. Change the name at the bottom and write "my son" or "my daughter" in the body.
Is it free, and is my file uploaded?
Yes, it is free, with no sign-up and no watermark. Your file is processed inside your browser and is never uploaded to a server.
