Philadelphia native Wendell W. Young III was one of the most important American labor leaders in the last half of the twentieth century. An Acme Markets clerk in the 1950s and ’60s, he was elected top officer of the Retail Clerks Union when he was twenty-four. His social justice unionism sought to advance wages while moving beyond collective bargaining to improve the conditions of the working-class majority, whether in a union or not. Young quickly gained a reputation for his independence, daring at times to publicly criticize the policies of the city’s powerful AFL-CIO leadership and tangle with the city’s political machine.
