"Revolutionary Union Movements” began as the Dodge Revolutionary Union Movement or DRUM in May 1968 at the Chrysler Hamtramck Assembly Plant (formerly Dodge Main). It was an attempt to redress problems in working conditions, particularly employment discrimination that had blacks restricted to the most menial or dangerous jobs, and kept from moving into better paying positions in the plants, at a time when neither the unions nor the government would respond to the issues. DRUM also wanted to increase the visibility of blacks in the unions. Their tactics included wildcat strikes, demonstrations, and publications. RUMs developed in other plants and industries. They were united under the League of Revolutionary Black Workers from 1969 to 1971.
