International Union of Bricklayers and Allied Craftworkers

The International Union of Bricklayers and Allied Craftworkers (BAC) is a labor union representing skilled workers in various masonry and trowel trades. Established in 1865, it is one of the oldest continuous unions in North America. BAC members specialize in working with brick, stone, marble, tile, terrazzo, and other masonry materials. Bricklayers construct walls, chimneys, and other structures using bricks, concrete blocks, and similar materials. Stone masons work with natural and artificial stone to create facades, decorative elements, and structural components. Tile setters install ceramic, mosaic, and marble tiles on floors, walls, and ceilings. Terrazzo workers create decorative flooring by embedding marble chips or other materials in cement and polishing the surface. Pointer-cleaner-caulkers (PCCs) maintain and restore masonry structures, performing tasks like repointing mortar joints and waterproofing. The union also represents marble masons, who work with marble and other stone in building interiors, and refractory workers, who install heat-resistant materials in high-temperature industrial settings. BAC provides comprehensive training programs to ensure its members maintain high skill levels in traditional techniques while adapting to new materials and technologies. The union advocates for fair wages, safe working conditions, and benefits for its members across the United States and Canada, playing a crucial role in maintaining quality standards in masonry and related crafts in the construction industry.
