strikers were shot and injured by local police, Governor Lehman threatened to replace policemen with National Guard troops unless local law enforcement authorities proved capable of more restraint. Contract talks begin in earnest in late July 1936, three months into the strike. The AFL had filed a variety of unfair labor practice (ULPs) charges against Remington Rand, but the company had won a temporary injunction halting any NLRB hearings on the ULPs in mid-July. Remington Rand officials were particularly concerned that NLRB hearings would expose their anti-union tactics. Company officials, worried that the United States Supreme Court and other federal courts would uphold the National Labor Relations Act, began negotiations as a fall-back strategy. Those negotiations collapsed on September 2, 1936. A major turning point in the strike came 10 days later. U.S. district court Judge John Knight lifted the temporary injunction and ordered the NLRB to proceed with its ULP hearings. The NLRB hearings, as well as United States Senate hearings into strikebreaking in general, began in late September. Evidence of the extensive anti-union campaign in the Remington Rand strike became public in late November 1936, and made national headlines. By March 1937, public exposure of the Remington Rand company's anti-union efforts had led to a significant deterioration in the firm's public support. The company did not cut back on its efforts, and rumor-mongering about plant closures and to demoralize workers was still effective. But public opinion and media opinion proved much harder to manipulate, and many elected officials were quietly withdrawing support for the company. On March 11, 1937, United States Secretary of Labor Frances Perkins attempted to mediate an end to the strike. When Perkins attempted to reach Rand by telephone, his aides claimed to not know where he was. When Perkins sent him telegrams and letters, company staff said they did not know how to reach him. Perkins was forced to publish an open letter in newspapers in Connecticut, New York and Ohio, asking Rand to speak to her. He did so the next day, but refused to discuss the strike with her. The incident embarrassed and angered Perkins, but Rand's rudeness further eroded the company's public standing. On March 13, 1937, the NLRB issued a decision finding Remington Rand guilty of violating federal labor law. The decision, Remington Rand, Inc., 2 NLRB 626, was an astonishing 120-page decision in which the Board recounted nearly every
