The most dramatic episode of workplace activism during this era was an illegal strike of more than 200,000 postal workers in March 1970. . . President Johnson suggested to Congress a modest pay increase for postal workers. Congress took no action, but in 1970 it offered them a puny 4 percent raise–and a week later voted itself a 41 percent salary increase… At one point Nixon mobilized the National Guard to sort and deliver the mail, but postal work was hard, skilled work and untrained soldiers could not easily perform it. The breakdown of discipline was palpable. Of the 26,000 soldiers called up to intervene in the strike, only 16,000 bothered to show. Within a matter of two weeks, the disproportionately Black postal workplace won a 14 percent wage increase.
