About BAC

John J. Flynn

Welcome to the International Union of Bricklayers and Allied Craftworkers (BAC), one of the oldest, most respected and highly skilled trade unions in the United States and Canada. Learn more about our proud history.

Today's BAC members are continuing the proud tradition of craft excellence and union solidarity started by our founders over a century ago. As you go through our website, you'll see the range of training, benefits and services that BAC members are able to access.

Members are encouraged to actively participate in the Union by attending local or chapter meetings, asking questions, making suggestions, expressing their concerns and voting in elections.

The information on this website is only a part of our story and what we have to offer masonry craftworkers and contractors. If you have additional questions, please contact us.
