Those who have used today to suggest that Dr. Martin Luther King Jr was not a progressive or was unconcerned with the right to organize are just plain lying.
"In our glorious fight for civil rights, we must guard against being fooled by false slogans, such as 'right to work.' It is a law to rob us of our civil rights and job rights. Its purpose is to destroy labor unions and the freedom of collective bargaining by which unions have improved wages and working conditions of everyone…Wherever these laws have been passed, wages are lower, job opportunities are fewer and there are no civil rights. We do not intend to let them do this to us. We demand this fraud be stopped." -- speaking about right-to-work laws in 1961
