National Association of Die Casting Workers
From Wikipedia, the free encyclopedia
The National Association of Die Casting Workers (NADCW) was a labor union representing workers involved in casting metal in the United States and Canada.
The union was founded in 1934,[1] largely on the initiative of Edward T. Cheyfitz, who became its national secretary.[2] In 1937, it affiliated to the Congress of Industrial Organizations,[1] at which time, it had about 4,750 members.[3] In 1942, it became part of the International Union of Mine, Mill and Smelter Workers.[1] By 1948, it had 20,000 members, at which time it transferred to the United Automobile Workers.[4]
