The Western Union man was an employee of Western Union in 1986. He arrived at Hill Valley High School during a history class on the first Monday in March, 1986 with a letter written by Clara Clayton in 1893, with instructions that it be delivered to Marty McFly at "the highest attainable level of education prior to university". The teacher told Marty to restrict his mail deliveries to his home address, but the letter deliverer mentioned that his supervisor at Western Union experienced a case like this when he was young.
