King Coal by Upton Sinclair

Edward would have endeavoured to carry his brother away forthwith, but there was no train until late at night; so Hal went upstairs, where he found Moylan and Hartman with Mary Burke and Mrs. Zamboni, all eager to hear his story. As the members of the committee, who had been out to supper, came straggling in, the story was told again, and yet again. They were almost as much delighted as the men in Reminitsky's. If only all strikes that had to be called off could be called off as neatly as that!

Between these outbursts of satisfaction, they discussed their future. Moylan was going back to Western City, Hartman to his office in Sheridan, from which he would arrange to send new organisers into North Valley. No doubt Cartwright would turn off many men -- those who had made themselves conspicuous during the strike, those who continued to talk union out loud. But such men would have to be replaced, and the union knew through what agencies the company got its hands. The North Valley miners would find themselves mysteriously provided with union literature in their various languages; it would be slipped under their pillows, or into their dinner-pails, or the pockets of their coats while they were at work.
