LIUNA represents more than 500,000 working men and women fighting for good wages and benefits, safer jobsites, more successful employers and having a strong voice that working people deserve all across North America! Members of the Laborers’ Union belong to one of the fastest-growing unions in North America. The Pacific Southwest Region represents 70,000 members and their families in Arizona, California, Hawaii and New Mexico. The Pacific Southwest Region formed “The Pacific Southwest Regional Organizing Coalition” in 1999 to raise our market share and footprint in the industries in which we represent.

April 13, 1903

With dangerous working conditions, poor wages and little respect on the job pervasive in the construction industry, The International Hod Carriers and Laborers Union of America is formed by 25 delegates from 17 cities meeting in Washington, D.C. to obtain a charter from the AFL. The first Constitution is published in three languages: English, German and Italian and Herman Lilien of Chicago is elected President.

The Charter Application claims:

  • Wrecking of buildings
  • Excavation of buildings
  • Digging of trenches, piers, foundations, holes, lagging and sheeting of excavations
  • Concrete installation of floors, foundations or any other (by hand or any other process), signaling, handling of concrete buckets
  • Tending Masons & Plasterers — mixing, handling all materials, building scaffolding, building of proofing centers, drying of masonry and plaster
  • Tending Carpenters
  • Clearing debris from buildings
  • Shoring, underpinning and renovating of old buildings
  • Handling of dimension stones



Laborers vote to contribute more funds to “be thoroughly prepared to meet the combined, organized opposition of the employing class.”

Laborers see economic gains; wages nearly double in Pittsburgh and the workday is reduced from 10 hours to 8.5 hours. Membership reaches 11,000 workers, many of them immigrants, as overall immigration to the U.S. reaches an all-time high of 1.3 million people in the year of 1907.

A conflict with Cement Workers over artificial stones, street paving, sidewalk, steps, concrete wall and floor, guniting and patching, water and fireproofing, all concrete construction and manufacture of cement occurs, resulting in The Executive Council awarding concrete construction to the Laborers and leaving manufacture of cement to the Cement Workers.

The union changes its name to “International Hod Carriers and Common Laborers’ Union”; the new charter added additional jurisdiction: work in connection with sewers, streets, and tunnels.

With the election of Franklin D. Roosevelt as President, a number of major Labor Laws were passed which set the tone for the way companies and Labor Unions interact today.

1931: The Davis-Bacon Act

A law to encourage and protect family-supporting wages is passed for construction workers on constructions, alterations or repairs of Federal buildings or Public Works projects under contract with the Federal government. The law requires payment by contractors and subcontractors on Federal construction projects of wages predetermined by the government, based upon the wage rates prevailing in the local area. The law continues to the present, preventing unscrupulous contractors from using public projects to force wages and community standards down.

1932: The Norris-LaGuardia Act

Guarantees Labor Unions freedom from injunctive interference by courts and declares “Yellow Dog Contracts” (agreements signed by an employee declaring that he would not join any Labor Organization or Union) contrary to public interest and makes them unenforceable. The Act also frees labor from regulation under anti-trust laws.
