Labor movements and workers' rights were central to the Industrialization era. As factories boomed and cities grew, workers faced dangerous conditions, exhausting hours, and poverty-level pay. Unions formed to fight for better treatment but ran into fierce opposition from employers, courts, and the federal government.
The struggle between labor and capital defined the late 1800s. Strikes and conflicts like the Haymarket Affair and the Pullman Strike revealed both the growing power of organized labor and its limits. Though workers were often defeated in the short term, these efforts raised public awareness and laid the groundwork for major reforms in the twentieth century.
Labor union development and strategies
Emergence and early labor organizations
The first national labor organizations appeared in the years after the Civil War, as industrialization made working conditions worse for millions of Americans.
- The National Labor Union (1866) was one of the first national labor organizations. Its main goal was winning an eight-hour workday, and it also pushed for improved conditions. It dissolved after the depression of 1873.
- The Knights of Labor (1869) grew into one of the largest labor organizations of the era, peaking at around 700,000 members in 1886. Unlike later unions, the Knights welcomed unskilled workers, women, and Black workers (though not Chinese immigrants). They promoted a cooperative vision of society rather than pure wage bargaining.
American Federation of Labor and union strategies
The American Federation of Labor (AFL), founded in 1886 under Samuel Gompers, took a different approach from the Knights. Instead of trying to organize all workers, the AFL focused on skilled workers organized by craft (carpenters, cigar makers, etc.). Gompers pursued "bread and butter" goals: better wages, shorter hours, and improved conditions through collective bargaining with employers.
Unions in this period used several key strategies:
- Strikes to pressure employers and draw public attention to their demands
- Boycotts of products or companies to exert economic pressure
- Collective bargaining to negotiate contracts securing better terms for workers
- Lobbying for legislation to protect workers' rights
The Industrial Workers of the World (IWW), founded in 1905, took a more radical approach. The IWW advocated for industrial unionism, meaning all workers in an industry would belong to one union regardless of skill level. They openly called for overthrowing the capitalist system, which put them at odds with both employers and the more moderate AFL.
Major labor conflicts and outcomes

Significant strikes and their consequences
Four major conflicts illustrate the violent tensions between labor and capital during this period:
-
Great Railroad Strike (1877) — Sparked by wage cuts during an economic depression, this strike spread across multiple states and became the first nationwide labor action in U.S. history. Violence and property destruction followed, and President Hayes sent federal troops to suppress the strike. It showed that labor unrest could paralyze the national economy.
-
Haymarket Affair (1886) — A peaceful rally in Chicago supporting the eight-hour workday turned deadly when someone threw a bomb at police, killing seven officers. Eight labor activists were tried, and four were executed despite thin evidence connecting them to the bombing. The incident turned public opinion against labor radicalism and badly damaged the Knights of Labor.
-
Homestead Strike (1892) — Workers at Carnegie Steel in Homestead, Pennsylvania, struck over wage cuts. The company hired Pinkerton detectives as a private armed force to break the strike, leading to a pitched battle that killed workers and Pinkertons alike. The state militia eventually restored order, and the union was crushed. This was a major setback for organizing in the steel industry.
-
Pullman Strike (1894) — Workers at the Pullman Palace Car Company struck over wage cuts and high rents in the company town. The American Railway Union, led by Eugene V. Debs, supported the strike with a nationwide boycott of Pullman cars, disrupting rail traffic across the country. President Grover Cleveland sent federal troops to break the strike, and Debs was jailed. The courts issued an injunction (a court order) against the union, setting a precedent for using judicial power against strikes.
Impact on the labor movement
The outcomes of these conflicts were mostly unfavorable to workers in the short run. Strikes were broken by force, unions were weakened, and labor leaders faced jail time or worse.
Yet these events still mattered. They forced the public and politicians to confront the reality of industrial working conditions. Each conflict built momentum toward the idea that workers deserved legal protections, even if those protections wouldn't arrive in full until the Progressive Era and the New Deal.
Challenges for workers in the late 19th century

Exploitative working conditions
- Workers commonly put in 12 to 16 hours per day, six days a week, leaving almost no time for rest or family.
- Wages were extremely low. Many workers earned barely enough to feed their families, keeping them trapped in poverty.
- Factories and mines lacked basic safety measures. Hazardous equipment, poor ventilation, and exposure to toxic substances led to frequent accidents, injuries, and deaths. Industries like mining and textile manufacturing were especially dangerous.
Vulnerable populations and lack of opportunities
- Child labor was widespread. Children as young as five worked in factories, mines, and mills, often for even lower wages than adults.
- Workers had no job security. They could be fired at any time, without warning or compensation.
- Discrimination based on race, gender, and ethnicity was the norm. Women and minority workers received lower wages for the same work, and many workplaces were segregated.
- Limited access to education kept most workers locked in low-paying jobs with little chance of advancement, reinforcing a cycle of poverty.
Government policies vs worker rights
Antitrust laws and their impact on unions
The relationship between government and labor was complicated, and often hostile to workers.
The Sherman Antitrust Act (1890) was designed to break up monopolies and business trusts. In practice, however, courts frequently applied it against labor unions, ruling that strikes and boycotts were illegal "restraints on trade." This turned a law meant to check corporate power into a weapon against organized labor.
The Clayton Antitrust Act (1914) tried to fix this by stating that labor unions were not illegal combinations in restraint of trade. Gompers called it "labor's Magna Carta." But narrow judicial interpretations limited its real-world impact, and courts continued to side with employers in many cases.
Court decisions and labor legislation
Courts and Congress sent mixed signals about workers' rights throughout this period:
- Lochner v. New York (1905) — The Supreme Court struck down a New York law limiting bakers to a 10-hour workday, ruling it violated employers' and workers' "liberty of contract." This decision made it much harder for states to regulate working conditions.
- Erdman Act (1898) — Prohibited discrimination against railroad workers for union membership and set up mediation for labor disputes. The Supreme Court later struck it down.
- Keating-Owen Child Labor Act (1916) — Banned interstate commerce in goods produced by child labor. The Supreme Court overturned it in Hammer v. Dagenhart (1918), ruling Congress had overstepped its commerce power. Federal child labor regulation wouldn't stick until the 1930s.
- Adamson Act (1916) — Established an eight-hour workday for railroad workers. This was a genuine victory for labor and set a precedent for future work-hour legislation.
The overall pattern in this era was that government policies and court decisions favored business interests over workers' rights. But the groundwork was being laid. The struggles of the Gilded Age would eventually lead to far more comprehensive protections under the New Deal, including the National Labor Relations Act (1935) and the Fair Labor Standards Act (1938).
