Every September, Americans celebrate Labor Day with parades, family gatherings, and a well-earned day of rest. But behind the holiday is the story of a man who believed in the dignity of working people. His name was Peter J. McGuire, a carpenter by trade and one of the most important voices in the labor movement.
In the late 1800s, America was growing quickly. Tradespeople were helping build up cities, but their work often came with long hours, unsafe conditions, and low pay were the reality for many families.
Peter J. McGuire, the son of Irish immigrants, understood these struggles firsthand. He became a passionate advocate for fair wages, safe working conditions, and the idea that every worker deserved not just a living, but a life beyond work.
In 1881, McGuire founded the United Brotherhood of Carpenters and Joiners of America, the union that today lives on across America and Canada.
A year later, he presented an idea that would change the way America honors its workers. That idea became Labor Day, first celebrated in New York City on September 5, 1882. By 1894, it was signed into law as a federal holiday, ensuring that working people would forever be recognized as the foundation of our nation’s success.
Labor Day is a reminder of everything the labor movement has fought for and won. Because of workers like McGuire and those who stood beside him, we enjoy the eight-hour workday, safer workplaces, fair wages, weekends, overtime pay, and the kinds of benefits that support families.

The story of Labor Day founding is still in motion today. Union carpenters continue McGuire’s mission, fighting for good jobs, safe worksites, and opportunities for the next generation through registered apprenticeship programs.
As we celebrate Labor Day, we remember Peter J. McGuire. He was not just a labor leader, he was a carpenter who believed in fairness for all working people. His vision lives on every time a union member stands up for what is right and every time a community recognizes the value of skilled, hardworking men and women.
