The March on Washington that took place on August 28, 1963 was focused on getting economic and social equality for African-American citizens. The full name of this march was the "March on Washington for Jobs and Freedom."
The goal in this march was to force the US federal government to make laws that would allow African-American citizens equal opportunities in the workplace and in society in general. At the time of this march, there was no federal law that protected African-Americans from workplace discrimination.
