Oil! by Upton Sinclair

Bunny's speculations upon the problem of capital and labor were not destined to remain academic. Spending his Christmas holidays at Paradise, he found Paul looking very serious, and asking what would be Dad's attitude towards the matter of unions in this field. There was an organizer for the carpenters here, and Paul had talked with him, and decided that it was his duty to join. Some of the men had joined secretly, but Paul wouldn't have any concealment in his relations with Mr. Ross. Bunny answered that his father didn't think much of unions, but he certainly wouldn't object to Paul's joining, if Paul thought it was right; anyhow they'd talk it out. So that evening they had a session, which wasn't quite the same as a class at high school.

Dad believed in organization; he always said that, and his formula would apply to workingmen -- at least in theory. But in practice Dad had observed that a labor union enabled a lot of officials to live off the work of the real workers; these officials became a class by themselves, a sort of vested interest, and they looked out for themselves, and not for labor. They naturally had to make some excuse for their own existence, and so were apt to stir up the workers to discontent which otherwise the workers wouldn't feel.
