About Us

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 diverse and effective unions representing public service employees.

LIUNA members are on the forefront of the construction industry – a sector that is a powerhouse of 12 million workers producing 5 percent of our countries’ economic output.

A half-million strong, we are united through collective bargaining agreements which help us earn family-supporting pay, good benefits and the opportunity for advancement and better lives.
