Since colonial times, striking has been a vital strategy for American labor, as fishermen, bakers, refuse collectors, and tailors sought better pay and fair treatment by refusing to work. Strikes played a significant role in the emergence of the organized labor movement, which gained momentum in the mid-to-late 1800s. Over the years, these actions contributed to numerous hard-fought victories for workers, leading to improved wages, the establishment of the eight-hour workday, and enhanced working conditions.
However, labor stoppages have also posed significant risks for workers. During the 1800s and early 1900s, picketers often faced violence from police or thugs hired by management. “The U.S. has one of the most violent labor histories in the world,” notes Judith Stepan-Norris, a research professor of sociology at the University of California. Keep reading to find out the 14 most essential strikes in the history of the United States that shaped the American workplace today.
Great Steel Strike (1919)

In the aftermath of World War I, the uneasy alliance between industrial companies, labor unions, and the U.S. government crumbled. In September 1919, a coalition of unions, including the American Federation of Labor and the Amalgamated Association of Iron, Steel, and Tin Workers, launched a nationwide strike against U.S. Steel.
The strike effectively paralyzed steel production, with 350,000 workers halting operations in mills across six states. However, it faced brutal suppression. Police and company-hired thugs attacked picketers, and tens of thousands of Black workers, excluded from unions due to racial prejudice, were brought in as strikebreakers. By January 1920, the AFL conceded defeat, marking a significant setback for the labor movement.
Flint Sit-Down Strike (1936-37)

In Flint, Michigan, the fledgling United Auto Workers (UAW) took on General Motors in a groundbreaking showdown that would transform labor relations. Rather than walking off the job, the auto workers pioneered the sit-down strike, occupying the plant and halting production.
For 44 days, workers held their ground, turning the factory floor into a temporary home. Security guards and police attempted to storm the plant with tear gas, but the workers fought back fiercely, resulting in the “Battle of the Running Bulls.” Their resilience paid off, marking a pivotal victory for the labor movement and inspiring similar actions nationwide.
Homestead Steel Strike (1892)

Imagine a time when the air was thick with tension, and the clang of steel echoed across the Monongahela River. Carnegie Steel’s vast Homestead plant was ground zero for a fierce clash between the Amalgamated Association of Iron and Steel Workers and Henry Clay Frick, the company’s chief executive determined to crush union power.
In June 1892, Frick slashed wages and shut out the workers, refusing any negotiation. To protect strikebreakers he planned to hire, Frick enlisted Pinkerton detectives, known for their ruthless union-busting tactics. Thousands of striking workers and their families rallied by the river to block their arrival. A bloody gunfight erupted, forcing the Pinkertons to surrender. This brutal confrontation marked a pivotal moment in labor history.
Pullman Strike (1894)

In the shadows of Chicago, George Pullman’s drastic measures sent shockwaves through his company town. In 1893, he laid off three-quarters of his workforce and cut wages for many others by nearly 30%, all while maintaining high rents and store prices in the company town. The following year, the American Railway Union (ARU), led by Eugene V. Debs, launched a nationwide boycott of trains carrying Pullman cars.
This sympathy action—the first in American labor history—saw rail travel halt across 27 states. However, the strike faced formidable opposition. President Grover Cleveland’s administration intervened, issuing an injunction and deploying 10,000 federal troops to break the strike. While many strikers were rehired, union leaders were blacklisted, and Debs served six months in prison. His time behind bars fueled his activism in the Socialist Party.
Bread and Roses Strike (1912)

In Lawrence, Massachusetts, textile mill workers faced a harsh reality when factory owners sped up production and cut wages in response to a new law reducing the workweek. Determined to fight back, about 25,000 immigrant workers—primarily women—shut down their looms and walked out in what became known as the “Bread and Roses Strike.”
When the AFL refused to support them, the strikers turned to the radical Industrial Workers of the World (IWW). The IWW organized relief efforts and led massive marches through the city’s commercial district, defying police and state militia. The strike garnered national attention when authorities tried to prevent children from boarding trains to safety, resulting in violent clashes.
Delano Grape Strike (1965-70)

In California, farm workers led by Cesar Chavez and Larry Itliong waged a five-year struggle for better pay and humane working conditions. They employed nonviolent tactics like marches and hunger strikes and garnered public support by urging a nationwide grape boycott.
Their perseverance paid off with a contract victory and the enactment of the California Agricultural Labor Relations Act of 1975, which granted collective bargaining rights to farm workers.
Postal Workers’ Strike (1970)

Frustrated by low wages and minimal raises, U.S. postal workers went on strike in March 1970 despite a federal ban on such actions. The strike quickly spread nationwide, becoming the largest walkout by federal employees.
In response, President Nixon called in the National Guard to deliver mail. After eight days, the strike ended with an immediate pay hike. Eventually, postal workers gained the right to negotiate salaries and working conditions with the formation of the USPS in 1971.
Air Traffic Controllers’ Strike (1981)

In the summer of 1981, nearly 13,000 air traffic controllers left the job after failed contract negotiations with the FAA. President Reagan ordered them back to work under a rarely-invoked law, and when most did not comply, he fired them and banned them from future government employment. This event marked a significant shift in federal and corporate attitudes towards unions, contributing to a decline in organized labor.
Memphis Sanitation Workers Strike (1968)

In February 1968, the tragic deaths of two Black Memphis trash collectors due to a faulty truck compactor ignited outrage among fellow workers, who earned only 65 cents per hour with no overtime or sick leave.
Defying an order from the mayor, 1,300 workers went on strike, and trash piled up across the city. This strike is notable as the backdrop for Dr. Martin Luther King Jr.’s assassination. After a powerful silent march led by Coretta Scott King, the city conceded to raise wages and recognize the workers’ union.
The Great Southwest Railroad Strike of 1886

The Great Southwest Railroad Strike, from March to September 1886, spanned Arkansas, Illinois, Kansas, Missouri, and Texas. This monumental strike involved approximately 200,000 workers. American railroads were rapidly expanding during this period, bringing new opportunities and significant challenges.
However, by 1886, the Knights of Labor members had had enough of the unsafe working conditions, grueling hours, and meager pay offered by their employers, the Union Pacific Railroad and the Missouri Pacific Railroad, both owned by the infamous Jay Gould.
McKees Rock Strike

In 1909, immigrant workers at the Pressed Steel Car Co. plant in McKees Rock, Pennsylvania, stood together in solidarity, defying exploitation and division. Eugene V. Debs, a leading union activist, hailed this as “the greatest labor fight” of his career.
This strike, which involved workers from 16 different nationalities, including Russians, Italians, and Germans, highlighted the power of unity despite language barriers. Their courage paved the way for significant changes in American unionism.
The Triangle Shirtwaist Fire

On March 25, 1911, a devastating fire at the Triangle Shirtwaist factory claimed the lives of 146 workers, most of whom were young women trapped by locked fire escape doors. This tragedy wasn’t just a horrific event but a catalyst for change, drawing widespread attention to workplace safety.
The aftermath saw a surge in activism, pushing for essential reforms and inspiring leaders like Frances Perkins, who later became the Secretary of Labor under President Franklin D. Roosevelt.
The Great Anthracite Coal Strike of 1902

The Great Anthracite Coal Strike saw 147,000 coal miners from the United Mine Workers of America (UMWA) in eastern Pennsylvania demanding better wages and working conditions. The strike, which lasted from May to October 1902, posed a significant threat to the nation’s energy supply, as the region housed the largest reserves of anthracite coal.
The situation grew so dire that President Theodore Roosevelt stepped in during the winter of 1903, fearing a heating crisis. Despite his efforts, the negotiations initially failed. It wasn’t until J.P. Morgan, an influential banker and industrialist, intervened, realizing the strike’s potential negative impact on his ventures, that a resolution was reached. The miners ultimately accepted a 10% pay raise, a compromise from their original demand for a 20% increase.
The United Mine Workers of America Strike of 1946

In 1946, the United Mine Workers of America orchestrated a significant April to December strike involving around 400,000 miners. This strike, known as the Bituminous Coal Strike, disrupted operations across more than 26 states. The miners fought for safer working conditions, health benefits, and fair wages.
President Harry Truman attempted to mediate a settlement, but his efforts were initially unsuccessful. In a dramatic move, he imposed a $3.5 million fine on the union and forced the miners to accept a deal, effectively ending the strike. Despite this, the strikers’ persistence paid off, resulting in a compromise, The Promise of 1946, formalized in the Krug-Lewis Agreement. This agreement established health and welfare funds for the miners, marking a significant victory for workers’ rights.
