The mine owners" Bill Haywood [View all]

William Dudley Haywood (February 4, 1869 – May 18, 1928), better known as "Big Bill" Haywood, was a founding member and leader of the Industrial Workers of the World (IWW) and a member of the executive committee of the Socialist Party of America. During the first two decades of the 20th century, he was involved in several important labor battles, including the Colorado Labor Wars, the Lawrence Textile Strike, and other textile strikes in Massachusetts and New Jersey.

Haywood was an advocate of industrial unionism,[1] a labor philosophy that favors organizing all workers in an industry under one union, regardless of the specific trade or skill level; this was in contrast to the craft unions that were prevalent at the time, such as the AFL.[2
