Strike action, also called labor strike, labour strike and industrial action in British English, or simply strike, is a work stoppage caused by the mass refusal of employees to work. A strike usually takes place in response to employee grievances. Strikes became common during the Industrial Revolution, when mass labor became important in factories and mines. As striking became a more common practice, governments were often pushed to act. When government intervention occurred, it was rarely neutral or amicable. Early strikes were often deemed unlawful conspiracies or anti-competitive cartel action and many were subject to massive legal repression by state police, federal military power, and federal courts. Many Western nations legalized striking under certain conditions in the late 19th and early 20th centuries.

Chartism was a working-class movement for political reform in the United Kingdom that erupted from 1838 to 1857 and was strongest in 1839, 1842 and 1848. It took its name from the People's Charter of 1838 and was a national protest movement, with particular strongholds of support in Northern England, the East Midlands, the Staffordshire Potteries, the Black Country and the South Wales Valleys, where working people depended on single industries and were subject to wild swings in economic activity. Chartism was less strong in places, such as Bristol, that had more diversified economies. The movement was fiercely opposed by government authorities, who finally suppressed it.
