About LiUNA

The Laborers’ International Union of North America is the most progressive, aggressive and fastest-growing union of construction workers, and one of the most significant unions representing public service employees.

Working men and women who carry a LiUNA membership card reside in every community across the U.S. and Canada, and come from every part of the world. We work on highways and bridges, waterways and dams, in universities and in government. We build and weatherize houses; and make cities, counties, states and the federal government work. From pouring concrete to handling mail, from helping the sick heal to helping the young learn, we literally and figuratively build America and Canada.
