Knights of Labor (K of L), officially Noble and Holy Order of the Knights of Labor, was the largest and one of the most important American labor organizations of the 1880s.
 Its most important leader was Terence V. Powderly.
 The Knights promoted the social and cultural uplift of the workingman, rejected socialism and anarchism, demanded the eight-hour day, and promoted the producers ethic of republicanism.
 In some cases it acted as a labor union, negotiating with employers, but it was never well organized, and after a rapid expansion in the mid-1880s, it suddenly lost its new members and became a small operation again.
James Duncan (May 5, 1857 – September 14, 1928) was a Scottish American union leader, and president of the Granite Cutters' International Association from 1885 until his death in 1928.
 He was an influential member of the American labor movement, helping to co-found the American Federation of Labor.
Frances Nacke Noel (January 5, 1873 – April 24, 1963) was a women’s labor activist and suffragette, and was known as "the most eloquent female orator of Southern California" in the early 20th century.
 Nacke acted as one of the primary female labor and suffrage leaders in the Los Angeles labor movement.
 She was one of the first "progressive activists" to tie to the suffragette movement to the labor movement, thereby achieving mutual goals of emancipation of both women and workers.
 Through her oration and organization, Nacke was a key contributor to the passing of the suffrage movement in Los Angeles.
 A large part of Nacke’s platform throughout her life was compromising the differences between class divisions in the labor movement.
Labor Notes is a non-profit organization and network for rank-and-file union members and grassroots labor activists.
 Though officially titled the Labor Education and Research Project, the project is best known by the title of its monthly magazine.
 The magazine reports news and analysis about labor activity or problems facing the labor movement.
 In its pages it advocates for a revitalization of the labor movement through Social Movement Unionism and union democracy.
 Labor Notes is based out of Detroit, Michigan with an East Coast office located in Brooklyn, New York.
Terence Vincent Powderly (January 22, 1849 – June 24, 1924) was an American labor union leader, politician and attorney, best known as head of the Knights of Labor in the late 1880s.
 He was elected mayor of Scranton, Pennsylvania for three 2-year terms, starting in 1878.
 A Republican, he served as the United States Commissioner General of Immigration in 1897.
 The Knights of Labor was one of the largest American labor organizations of the 19th century, but Powderly was a poor administrator and could barely keep it under control.
 His small central office could not supervise or coordinate the many strikes and other activities sponsored by union locals.
 Powderly believed that the Knights was an educational tool to uplift the workingman, and he downplayed the use of strikes to achieve worker goals.
Robert Fechner (22 March 1876 – 31 December 1939) was a national labor union leader and director of the Civilian Conservation Corps (1933–39), which played a central role in the development of state and national parks in the United States.
 Born in Chattanooga, Tennessee.
 With only a public school elementary education he had risen to become an American labor union leader and vice president of the International Association of Machinists.
 He had a reputation for fairness, tact, and patience in all his dealings.
 On 5 April 1933 he was appointed by President Franklin Delano Roosevelt to be the Director of the Civilian Conservation Corps (CCC).
 It was Fechner's fairness and ability for organization and administration that impressed the president to his appointment as director.
 Although he had been an important labor figure, Fechner objected to attempts of union organizers to form unions among CCC enrollees in the camps.
 He felt that the government was doing all it possibly could for the well-being of the enrollees: well fed, supporting dependents with monthly earnings, getting an education; and they were contributing in a constructive manner to the conservation needs of the nation.
 The need for a union in this situation was not necessary, and he issued orders to keep union organizers out of the CCC camps and gave instructions that if any of the CCC enrolees joined a union they were to be discharged.
 Upon Fechner's death while still serving as CCC Director he was succeeded by James McEntee.
Dan Rush is an American union organizer and former statewide political and special operations director of the United Food and Commercial Workers for cannabis and hemp worker.
 He is known for being a leader in the United States Labor movement in politics and for cannabis and hemp industry workers, and a civil and motorcycle rights activist.
 Rush began his career in the union in the 1980s as a senior official responsible for carrying out statewide ballot industry politics and eventually founded the concept of organizing medical cannabis and hemp workers in the United States and Canada.
 He was later investigated by the FBI for allegedly breaching union discipline in 2015, by influencing unions’ decisions for bribes from cannabis and hemp industry stakeholders.
Labor Express Radio is a weekly labor news and current affairs radio program that broadcasts every Monday morning on WLUW, a formerly-independent community radio station in Chicago which has recently reverted to its original status as the radio station for Loyola University in Chicago.
 It is Chicago’s only English-language radio program devoted to issues related to the labor movement ("Radio Chamba", also on WLUW covers the labor movement in its Spanish-language broadcast) and one of only a handful of such programs around the country.
 "Labor Express" has covered local, national and international labor news for almost a decade and a half, since its first broadcast in 1993.
 It is a totally volunteer-produced and self-funded project.
 The program is a production of the "Committee for Labor Access", a 501(c)(3) non-profit organization, which oversees both "Labor Express" and "Labor Beat", a Public-access television labor cable TV program which broadcasts in Chicago and Rockford, Illinois and St. Louis, Missouri.
 The program is affiliated with IBEW Local 1220 which represents radio and TV broadcast engineers in Chicago, but the views expressed on the show are solely that of its producers.
William H. Sylvis (1828–1869) was a pioneer American trade union leader.
