How will you make a letter of explanation to your boss?

A Letter to the Boss: ---- From: Your name, address, phone, email. To: The boss's name, and the address of his/her work place. Date: Subject: eg. Request to start work one hour later. Dear Sir/Miss/Ms/Madam, (or their full name) I write to ask if I may start work one hour later on Monday of next week due to the fact that I need to deliver my car to a repair shop across town before catching a bus to work. I would appreciate your allowing me to do this and hope you will agree to this request. Yours faithfully, (Your signature, employee number, designation, etc.) ---- Note: Your letter should be short, simple, polite and honest as you explain whatever needs to be explained.
