The men and women of LIUNA do the hard, dangerous and sometimes dirty work of building our countries.

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.
