The union's history has numerous examples of strikes in which members and their supporters clashed with company-hired strikebreakers and government forces. The most notable include:
1890s •
Morewood massacre – April 3, 1891, in
Morewood, Pennsylvania. A crowd of mostly immigrant strikers were fired on by deputized members of the 10th Regiment of the National Guard. At least ten strikers were killed and dozens injured. •
Bituminous Coal Miners' Strike of 1894 – April 21, 1894. This nationwide strike was called when the union was hardly four years old. Many of the workers salaries had been cut by 30% •
1908 Alabama coal strike – June–August 1908. Notable because the 18,000 UMWA-organized strikers, more than half of those working in the
Birmingham District, were racially integrated. That fact helped galvanize political opposition to the strikers in the segregated state. The governor used the Alabama State Militia to end the work stoppage. The union adopted racial segregation of workers in Alabama in order to reduce the political threat to the organization. •
Westmoreland County Coal Strike – 1910–1911, a 16-month coal strike in
Pennsylvania led largely by
Slovak immigrant miners, this strike involved 15,000 coal miners. Sixteen people were killed during the strike, nearly all of them striking miners or members of their families. •
Colorado Coalfield War – September 1913–December 1914. A frequently violent strike against the
John D. Rockefeller Jr.-
Colorado Fuel and Iron company. Many strikers and opposition were killed before the violent reached a peak following the April 20, 1914
Ludlow Massacre. An estimated 20 people, including women and children, were killed by armed police, hired guns, and
Colorado National Guardsmen who broke up a tent colony formed by families of miners who had been evicted from company-owned housing. The strike was partially led by
John R. Lawson, a UMWA organizer and saw the participation of famed activist
Mother Jones. The UMWA purchased part of
Ludlow site and constructed the
Ludlow Monument in commemoration of those who died. •
Hartford coal mine riot – July 1914. The surface plant of the Prairie Creek coal mine was destroyed, and two non-union miners murdered by union miners and sympathizers. The mine owners sued the local and national organizations of the United Mine Workers Union. The national UMWA was found not complicit, but the local was judged culpable of encouraging the rioters, and made to pay US$2.1 million. •
United Mine Workers coal strike of 1919 – November 1, 1919. Some 400,000 members of the United Mine Workers went on strike on November 1, 1919, although Attorney General
A. Mitchell Palmer had invoked the
Lever Act, a wartime measure criminalizing interference with the production or transportation of necessities, and obtained an injunction against the strike on October 31. The coal operators smeared the strikers with charges that Russian communist leaders
Lenin and
Trotsky had ordered the strike and were financing it, and some of the press repeated those claims. •
Matewan, West Virginia – May 19, 1920. 12 men were killed in a gunfight between town residents and the
Baldwin–Felts Detective Agency, hired by mine owners. Director
John Sayles directed a feature film,
Matewan, based on these events. • The 'Redneck War' – 1920–21. Generally viewed as beginning with the Matewan Massacre, this conflict involved the struggle to unionize the southwestern area of West Virginia. It led to the march of 10,000 armed miners on the county seat at
Logan. In the
Battle of Blair Mountain, miners fought state militia, local police, and mine guards. These events are depicted in the novels
Storming Heaven (1987) by Denise Giardina and
Blair Mountain (2005) by Jonathan Lynn. •
1920 Alabama coal strike, a lengthy, violent, expensive and fruitless attempt to achieve union recognition in the coal mines around
Birmingham left 16 men dead; one black man was
lynched. •
1922 UMW General coal strike, On April 1, 1922, 610,000 mine workers struck nationwide, shutting down the majority of operations within the country. •
Herrin massacre occurred in June 1922 in
Herrin, Illinois. 19 strikebreakers and 3 union miners were killed in mob action between June 21–22, 1922.
1922–1925 Nova Scotia strikes In the 1920s, about 12,000 Nova Scotia miners were represented by the UMWA. These workers lived in very difficult economic circumstances in
company towns. The
Dominion Steel and Coal Corporation, also known as the British Empire Steel Corporation, or BESCO, controlled most coal mines and every steel mill in the province. BESCO was in financial difficulties and repeatedly attempted to reduce wages and
bust the union. Led by
J. B. McLachlan, miners struck in 1923, and were met by locally and provincially-deployed troops. This would eventually lead to the federal government introducing legislation limiting the civil use of troops. In 1925 BESCO announced that it would not longer give credit at their
company stores and that wages would be cut by 20%. The miners responded with a strike. This led to violence with
company police firing on strikers, killing miner
William Davis, as well as the looting and arson of company property. This crisis led to the Nova Scotia government acting in 1937 to improve the rights of all wage earners, and these reforms served as a model across Canada, at both provincial and federal levels.
The Brookside Strike In the summer of 1973, workers at the
Duke Power-owned Eastover Mining Company's Brookside Mine and Prep Plant in
Harlan County, Kentucky, voted to join the union. Eastover management refused to sign the contract and the miners went on strike. Duke Power attempted to bring in replacement non-union workers or "
scabs" but many were blocked from entering the mine by striking workers and their families on the picket line. Local judge F. Byrd Hogg was a coal operator himself and consistently ruled for Eastover. During much of the strike the mine workers' wives and children joined the picket lines. Many were arrested, some hit by baseball bats, shot at, and struck by cars. One striking miner, Lawrence Jones, was shot and killed by a
Strikebreaker. Three months after returning to work, the national UMWA contract expired. On November 12, 1974, 120,000 miners nationwide walked off the job. The
nationwide strike was bloodless and a tentative contract was achieved three weeks later. This opened the mines and reactivated the railroad haulers in time for Christmas. These events are depicted in the documentary film
Harlan County, USA.
The Pittston strike The
Pittston Coal strike of 1989-1990 began as a result of a withdrawal of the Pittston Coal Group also known as the
Pittston Company from the
Bituminous Coal Operators Association (BCOA) and a refusal of the Pittston Coal group to pay the health insurance payments for miners who were already retired. The owner of the Pittston company at the time, Paul Douglas, left the BCOA because he wanted to be able to produce coal seven days a week and did not want his company to pay the fee for the insurance. The Pittson company was seen as having inadequate safety standards after the
Buffalo Creek flood of 1972 in which 125 people were killed. The company also was very financially unstable and in debt. The mines associated with the company were located mostly in Virginia, with mines also in West Virginia and Kentucky. On 31 January 1988 Douglas cut off retirement and health care funds to about 1500 retired miners, widows of miners, and disabled miners. To avoid a strike, Douglas threatened that if a strike were to take place, that the miners would be replaced by other workers. The UMW called this action unjust and took the Pittston company to court. Miners worked from January 1988 to April 1989 without a contract. Tension in the company grew and on April 5, 1989, the workers declared a strike. Many months of both violent and nonviolent strike actions took place. On 20 February 1990 a settlement was finally reached between the UMWA and the Pittston Coal Company. ==Internal conflict==
