Through the 2007–08 school year, Emerson High School was one of two high schools to serve Union City, along with Union Hill High School. The last graduating class for both schools was in June 2008. The student bodies of both schools were to merge into the new Union City High School, which is housed in a building on the site of the former Roosevelt Stadium. The switch was originally planned for September 2008, but the school was not completed by then, and pending the completion, Union Hill and Emerson became known as the north and south campuses of Union City High School, respectively. The new school opened September 3, 2009, with Emerson and Union Hill High Schools converting into middle schools.
