How did union strikes contribute to rising racial tensions in the 1920s?

Union strikes in the 1920s often exacerbated racial tensions as they frequently reflected the broader social and economic inequalities of the time. Many labor unions, dominated by white workers, sometimes excluded or discriminated against Black workers, leading to feelings of resentment and division within the working class. Strikes could also draw in racially charged rhetoric, as competition for jobs intensified between white and Black laborers, further fueling animosity. Additionally, when strikes turned violent, racial minorities were often scapegoated, deepening societal divides.
