Our History & Future


Cement Masons'

The Cement Masons' have serviced many industries in our jurisdiction including Automotive, Commercial/Retail, Healthcare/Hospital, Industrial/Manufacturing, Power/Solar, Warehouse, Worship, and more.

The Cement Masons' were one of the first building trades' unions in the area to offer a certified apprenticeship program. Pensions that are available to our members are the finest in the industry. The combination of our Health and Welfare plan, Pension, and Annuity plans gives our members financial security while working in the trade, but also through retirement. Through the efforts of the local union and our contractors, the amount of work in the area for Cement Masons continues to increase, and we look forward to a prosperous future.


The Operative Plasterers represent one of the most noble crafts in the greater Toledo area. In 1946 the union joined with the Contracting Plasterers' International Association. Through this program the union was able to guarantee a steady flow of qualified plasterers' to the ever expanding construction industry. We recently celebrated our International unions 150th anniversary and are proud to be members of the oldest building and construction trades union in the United States, tracing our roots back to 1864.






Our History

As the oldest Building and Construction trades' union in the United States, Our organization traces its roots back to 1864, during the American Civil War, when an organization known variously as the National Plasterers Union or National Plasterers Organization began to unify the local craft unions that represented workers in the trade.

The new union endorsed the eight hour work day movement while pledging to avoid "unnecessary strikes" and instituted apprenticeship training and regulations. In 1887 the union amended its constitution to include Canadian workers. Reflecting the fact that its members did more than just finish cement, the union in 1951 changed its name to the Operative Plasterers' and Cement Masons' International Association.

Today the OPCMIA continues to live by the principles that it was founded and which will continue to be its strength in the future. As its always been the OPCMIA continues to be Proud, Strong and United.
