Building a Better Life for Working Families

The International Brotherhood of Boilermakers represents nearly 50,000 skilled craftsmen and women across more than 200 local lodges in the United States and Canada. Since 1880, we've united workers in construction, shipbuilding, manufacturing, railroads, and dozens of other industries.

Our mission is simple: improve the lives of our members and their families through safer workplaces, stronger wages, world-class training, and national funds for pensions, health care, and retirement security.
