LIUNA’s History

Samuel_Gompers.jpgOn March 12, 1903, the great Samuel Gompers, President of the American Federation of Labor (AFL) called upon laborers throughout the country to form an international union of building laborers.

Heeding the call, on April 13, 1903, twenty-five delegates voted to form what we now know as LIUNA – the Laborers’ International Union of North America. 

On that date, the delegates adopted the following “Declaration of Principles:” 


LIUNA was founded by immigrants.





For 114 years, LIUNA has fought for the rights of working men and women of all races and nationalities.  It’s why we’re one of the largest and most diverse unions in America.  And it’s why we’ll continue to fight to protect the rights and safety of laborers, both on and off the job site.
