What local 40 plaster & cement masons does

OPCMIA Local Union 11 (Operative Plasterers' and Cement Masons' International Association Local 11) is a U.S. labor union local chartered under the international OPCMIA organization, representing plasterers and cement masons across eight designated geographic areas in northern Illinois and eastern Iowa. Headquartered at 1102 Rail Drive in Woodstock, Illinois, the local serves members in counties including Kankakee, Iroquois, Will, Grundy, La Salle, Bureau, Putnam, Lake, Winnebago, Boone, McHenry, Kane, DeKalb, Kendall, Jo Daviess, Stephenson, Carroll, Ogle, Whiteside, and Lee in Illinois, plus Dubuque, Delaware, Allamakee, Clayton, Jackson, and the eastern half of Jones in Iowa. The local is governed by elected officers including a President, Business Manager/Financial Secretary, Recording Secretary, and an Apprenticeship Coordinator, with area-level contacts covering each sub-region.

The union's core operations consist of three interconnected functions: (1) collective bargaining with signatory contractors to establish wage scales and working conditions — current cement mason and operative plasterer wage scales are published as effective June 1, 2026; (2) apprenticeship program administration to recruit and train new entrants to the trades; and (3) member services including dues and fee administration, wage reporting, benefits management, reciprocity arrangements for members working outside their home area, and contract enforcement. The local also maintains a public-facing website (opcmialocal11.com) providing resources for prospective members, current members, and contractors.

The local generates revenue through recurring membership dues collected from individual plasterers and cement masons. There is no commercial product or service revenue stream, no published dues schedule, and no disclosed financial figures. The organization is structured as a nonprofit private membership entity with no public ticker, no venture or institutional funding, and no disclosed subsidiaries. It operates as part of the international OPCMIA federation, which claims over 150 years of continuous representation and training history for the two trades.
