Born of strife and struggle, LIUNA members have been uniting for better lives since 1903.

LIUNA today honors a heritage that began in 1903 when courageous workers overcame hostility, threats and violence to join together for better lives. We honor that heritage through current struggles — being heard in government, raising standards for workers and employers on the job, and reaching out to a new generation of workers yearning for a better life.

Throughout recent history, LIUNA members have been at the forefront of the construction industry – which today is an economic powerhouse of 12 million working men and women who produce 5 percent of the gross domestic product of the U.S. and Canada.
