The 19th century was a period of great economic, political and industrial changes in the United States. The wealthy prospered in ways never seen before, and the growing gap between rich and poor created tensions that would shape an entire movement. Although the Labor Movement predates the 1800s, its effectiveness was largely shaped by the rampant inequalities ushered in by the industrial boom of the 19th century.

Violent Strikes and Demonstrations

Decades after the industrial revolution, tensions increased between the working class and the elite. Workers began to form into protective groups to air their grievances. With roots in socialism, an ideology popular in working class groups, labor organizations such as the American Federation of Labor formed to support workers. Though many labor groups pressed for nonviolent demonstrations, tensions often resulted in deadly violence. The Haymarket Affair of 1886 and the Pullman Strike of 1894 both led to deaths on both sides -- and further deepened the divide between the working class and those who reaped the benefits of their labor.

Poor Working Conditions

Working conditions of the 1800s left much to be desired. Factory workers were crammed into small spaces with hot, unsafe machines. Miners and loggers were paired with inefficient and dangerous machines that made work faster but also more dangerous. As the death toll rose, pressures to create safety standards increased. Labor unions around the country organized demonstrations to demand safety gear, proper ventilation, fire preparedness and many other important safeguards. Machines and harsh work claimed thousands of lives before legislation of the 1930s began to regulate safety in the workplace.

The Eight-Hour Workday

Workers in the 1800s often clocked over 16 hours of work per day. With the nation's poor clamoring for work, companies were able to get virtually unlimited work with little regulation for decades. In 1884, the AFL insisted on eight-hour workday regulations, and on May 1, 1886, over 300,000 workers across the country walked off the job to demand it. Though federal regulations weren't won until 1937, movements around the country made an impact decades before that. The United Mine Workers won the eight-hour day in 1898. The Building Trades Council followed two years later.

Child Labor

Large production machines made it possible for children to do work that had previously required the strength of men -- and for much less. Two million school-aged children held jobs by 1810. Factories and mines worked children over 12 hours per day. Working up to 70 grueling hours per week for under $1 per day, some who lived under the care of factory owners were required to work overnight. Labor organizations, churches, teachers and human rights activists vocally opposed child labor, forcing individual states to begin regulating the practice in 1813. By the end of the century, 28 states had adopted laws to regulate child labor. Federal child labor laws were passed in 1938.
