One significant example of a Black-led labor strike in Black history is the Brotherhood of Sleeping Car Porters strike in 1925. The Brotherhood of Sleeping Car Porters was the first labor union led by African Americans to receive a charter in the American Federation of Labor. The union was founded by A. Philip Randolph and Milton P. Webster, with the goal of improving working conditions for Pullman Company porters, who were predominantly Black.

In 1925, the union began a campaign to demand better pay, shorter working hours, and improved working conditions for the porters. The Pullman Company, which operated luxury sleeper cars on trains, had a history of exploiting Black workers and paying them low wages. The company resisted the union's demands and refused to recognize the Brotherhood of Sleeping Car Porters as a legitimate labor organization.

Despite facing opposition from the Pullman Company, the Brotherhood of Sleeping Car Porters continued to organize and mobilize porters across the country. The union eventually called for a strike in 1925, which was a bold and courageous move given the racial and economic challenges facing Black workers at the time.

The strike was not immediately successful, and the Pullman Company used various tactics to break the strike and undermine the union's efforts. However, the Brotherhood of Sleeping Car Porters persisted in their struggle, and their persistence eventually paid off. In 1937, after years of organizing, negotiating, and mobilizing support, the union successfully secured a landmark contract with the Pullman Company that included wage increases, improved working conditions, and other benefits for the porters.

The Brotherhood of Sleeping Car Porters strike was a pivotal moment in Black labor history, as it demonstrated the power of collective action and solidarity in the fight for workers' rights. It also highlighted the leadership and resilience of Black workers in the face of discrimination and oppression.
