The relationship between organized labor and the civil rights movement proceeded along two tracks. At work, the two groups were adversaries, as civil rights groups criticized employment discrimination by the unions. But in politics, they allied. Unions and civil rights organizations partnered to support liberal legislation and to oppose conservative southern Democrats, who were as militant in opposing unions as they were fervent in supporting white supremacy.
At work, unions dithered in their efforts to root out employment discrimination. Their initial enthusiasm for Title VII of the 1964 Civil Rights Act, which outlawed employment discrimination, waned the more the new law violated foundational union practices by infringing on the principle of seniority, emphasizing the rights of the individual over the group, and inserting the courts into the workplace. The two souls of postwar liberalism— labor solidarity represented by unions and racial justice represented by the civil rights movement—were in conflict at work.
Although the unions and civil rights activists were adversaries over employment discrimination, they united in trying to register southern blacks to vote. Black enfranchisement would end the South’s exceptionalism and the veto it exercised over liberal legislation in Congress. But the two souls of liberalism that were at odds over the meaning of fairness at work would also diverge at the ballot box. As white workers began to defect from the Democratic Party, the political coalition of black and white workers that union leaders had hoped to build was undermined from below. The divergence between the two souls of liberalism in the 1960s—economic justice represented by unions and racial justice represented by civil rights—helps explain the resurgence of conservatism that followed.
