International Union of Bricklayers & Allied Craftworkers

What International Union of Bricklayers & Allied Craftworkers does

The International Union of Bricklayers & Allied Craftworkers (BAC/IUBAC) is a private, non-profit labor union founded in 1865 in Washington, D.C., recognized as the oldest continuous union in North America. It represents skilled trowel trades craftworkers across eight crafts — brick, tile, stone, marble, terrazzo, cement, plaster, and PCC/Restoration — organized through Locals and Administrative District Councils in five regions spanning the Northeast, North Central, South, West, and Canada. Members access representation, collective bargaining, training, and a portfolio of benefits including the International Pension Fund, International Health Fund, Member Assistance Program, Disaster Relief Fund, scholarships, and tool purchasing.

BAC's core product surface centers on a secure Member Portal exposing membership data, work history, pension and health benefits, and the BAC Job Network (a bulletin-board system that routes craftworkers to labor-short Locals). Two wholly owned subsidiaries, the International Masonry Institute (IMI) and the International Masonry Training and Education Foundation (IMTEF), deliver standardized apprenticeship, certification, and contractor skills development in cooperation with signatory contractors. The organization also publishes the quarterly BAC Journal and operates social channels across YouTube, Facebook, X, Instagram, and TikTok.

Revenue is generated through recurring membership dues set by the Union's Constitution and varying by Local/ADC; figures are not publicly disclosed. BAC's go-to-market combines a sales-led organizing model (signatory contractor agreements and apprenticeship recruiting) with a community-led member engagement model emphasizing solidarity, training access, and advocacy. Strategic positioning rests on labor law protections (prevailing wage, Project Labor Agreements) and deep integration with AFL-CIO, NABTU, TCAA, ICE, CPWR, and the Canadian Labour Congress.
