The JLC understood that much remained to be done, not only overseas but at home. A new world had to be fashioned from the ashes and bitterness of war. Jacob Pat wrote,

Our work over here and over there, our Jewish work and our international work -- it is all one closely linked chain. We believe that there can be no good world that would be bad for the Jewish people, nor can there be a bad world that would be good for the Jewish people .... Our fight for a better America is equivalent to a fight for the American people, for the American labor movement; it is [a] fight for humanity and brotherhood. This is our fight also for the protection of the most injured masses, the Jewish masses. ("Story of the JLC," 1948.)

In the years immediately following the War, the JLC's Committee to Combat Anti-Semitism, in cooperation with the Anti-Defamation League of B'nai B'rith and the Negro Labor Committee, became the driving force behind AFL and CIO educational efforts in the field of human rights. The National Trade Union Council for Human Rights was chaired by the JLC's Charles Zimmerman, and JLC staff members helped to form committees to combat intolerance in more than twenty American cities. The JLC supplied posters, pamphlets, and film strips, organized classes, conferences and summer institutes, and generally stimulated awareness of the evil of race hatred throughout the labor movement.
