WHAT IS THE DIFFERENCE BETWEEN INTERNATIONAL UNIONS AND LOCAL UNIONS?


The International Unions are major organizations in which local unions receive charters to operate in certain areas. Our International “The Operative Plasterers & Cement Masons International Association of the United States and Canada (OP & CMIA) was formed during the Civil War, 1864. It has 105 local unions throughout the United States and Canada. Our Local was chartered in 1916.
