Howard Jenkins, Jr. with President Lyndon Johnson
Jenkins was appointed to the National Labor Relations Board (NLRB) in 1963 by the Democratic President Kennedy despite his life-long affiliation with the Republican party. His appointment coincided with the landmark civil rights legislation proposed by President John F. Kennedy, which was supported by civil rights organizations and their historic march on Washington, D.C., in 1963. The day after the historic march, Howard Jenkins, Jr., was sworn in as a member of the NLRB.
Out of respect for Dr. Martin Luther King and the civil rights march on Washington, Jenkins postponed his swearing-in ceremony until August 29, 1963. During his acceptance speech, Jenkins said, I know that it has not escaped your attention that I am a Negro. I am conscious of the inter-relationship between the problems of the Negro in the work force and the myriad of problems of our industrial economy. He confirmed that much of what was said and done in the past is equally relevant in the present.
Early in his tenure at the NLRB, Jenkins left no doubt that his voice would be remembered as one of those brave individuals who spoke out unflinchingly for the equality of all Americans. Shortly after his appointment to the Board, Jenkins addressed the Urban League of Kansas City. He described the plight of African American workers during that time:
I hold the conviction that no lasting solution is to be found in the many faceted racial problem in the United States unless provision is made for rescuing the masses of Negroes from economic oblivion to which they are otherwise consigned in this age of automation.
