When Peter McGuire was 17, he began an apprenticeship in a piano shop. This job was better than his others, for he was learning a trade, but he still worked long hours with low pay. At night he went to meetings and classes in economics and social issues of the day. One of the main issues of concern pertained to labor conditions. Workers were tired of long hours, low pay and uncertain jobs. They spoke of organizing themselves into a union of laborers to improve their working conditions. In the spring of 1872, Peter McGuire and 100,000 workers went on strike and marched through the streets, demanding a decrease in the long working day.
This event convinced Peter that an organized labor movement was important for the future of workers' rights. He spent the next year speaking to crowds of workers and unemployed people, lobbying (游说) the city government for jobs and relief money. It was not an easy road for Peter McGuire. He became known as a "disturber of the public peace." The city government ignored his demands. Peter himself could not find a job in his trade. He began to travel up and down the east coast to speak to laborers about unionizing (成立工会). In 1881, he moved to St. Louis, Missouri, and began to organize carpenters there. He organized a convention of carpenters in Chicago, and it was there that a national union of carpenters was founded. He became General Secretary of the United Brotherhood of Carpenters and Joiners of America.
On September 5, 1882 the first Labor Day parade was held in New York City. Twenty thousand workers marched in a parade up Broadway. They carried banners that read "LABOR CREATES ALL WEALTH," and "EIGHT HOURS FOR WORK, EIGHT HOURS FOR REST, EIGHT HOURS FOR RECREATION!" After the parade there were picnics all around the city. Workers and celebrants ate Irish stew, homemade bread and apple pie. At night, fireworks were set off. Within the next few years, the idea spread from coast to coast, and all states celebrated Labor Day.
