Abstract: Records, 1890-1990 (bulk 1899-1982), of the Retail Clerks International Union (most of which are on microfilm produced by the RCIU) documenting various departments and levels of the organization, from the executive office to the union locals. The RCIU began as the Retail Clerks International Protective Association around 1891, and eventually merged with the Amalgamated Meat Cutters and Butcher Workmen of North America in 1979 to become the United Food and Commercial Workers (UFCW). The collection spans the organization's history and includes organizing materials, financial records, collective bargaining files, correspondence, reports, memos, trusteeship files, convention proceedings, extensive administrative files, information on strikes and the Meat Cutters union, photographs, and sound recordings.
