https://en.wikipedia.org/wiki/Pullman_Strike#Background

Low wage, expensive rent, and the failing ideal of a utopian workers settlement were already a problem for the Pullman workers. Company towns, like Pullman, were constructed with a plan to keep everything within a small vicinity to keep workers from having to move far. Using company-run shops and housing took away competition leaving areas open to exploitation, monopolization, and high prices. These conditions were exacerbated by the Panic of 1893. George Pullman had reduced wages 20 to 30% on account of falling sales. However, he did not cut rents nor lower prices at his company stores, nor did he give any indication of a commensurate cost of living adjustment. The employees filed a complaint with the company's owner, George Pullman. Pullman refused to reconsider and even dismissed the workers who were protesting. The strike began on May 11, 1894, when the rest of his staff went on strike. This strike would end by the president sending U.S. troops to break up the scene.
