Hailed as one of the most important strikes in American history, the 44-day strike in Flint, Michigan, ended when General Motors recognized the United Auto Workers as the sole bargaining unit for its workers. Within a year, the UAW saw its membership grow from 30,000 to 500,000 members. The Flint Sit-down Strike was, as the British Broadcasting System later noted, "the strike heard 'round the world."
