Board of Education.

This Day In American History

The United Mine Workers of America (UMWA) were formed on this day in 1890 after the consolidation of workers from the Knights of Labor and the American Federation of Labor. The labor movement took its first burgeoning steps forming a united front in the fight to use collective bargaining as a negotiation tool in their battle against the scandalous working conditions that permeated the mining industry throughout the country. By the 1930 when the National Recovery Act would be signed into law organizers would be moving freely throughout the country to organize all coal miners.
