Bancroft Library - California Labor Union Collections

Overview of Bancroft Library's holdings on California Labor Unions.


Labor in California has had a complex history, often quite volatile. Political and frequently exclusionary, the early labor movement was characterized by the strong opinions of strong leaders. Archival records related to labor contain publications, reports, studies, press releases, and other materials on union activity as well as opposition to union efforts.

Resources on California labor include extensive documentation of various unions during the 20th century. Especially strong is documentation of the predominantly African-American Sleeping Car Porters’ Union and the International Longshoremen’s and Warehousemen’s Union under Harry Bridges (1901-1990), leader of the 1934 longshoremen’s strike.

This guide features highlights from The Bancroft Library's collections relating to labor unions in California.
