King Coal by Upton Sinclair

Hal was so startled by this discovery that he stopped in his tracks and gazed at the man. He had heard a lot about "troublemakers" in the camps, but so far the only kind he had seen were those hired by the company to make trouble for the men. But now, here was a union organiser! Jerry had suggested the possibility, but Hal had not thought of it seriously; an organiser was a mythological creature, whispered about by the miners, cursed by the company and its servants, and by Hal's friends at home. An incendiary, a firebrand, a loudmouthed, irresponsible person, stirring up blind and dangerous passions! Having heard such things all his life, Hal's first impulse was of distrust. He felt like the one-legged old switchman who had given him a place to sleep, after his beating at Pine Creek, and who had said, "Don't you talk no union business to me!"

Seeing Hal's emotion, the organiser gave an uneasy laugh. "While you're hoping I'm not a ‘dick,' I trust you understand I'm hoping you're not one."
