Arrowsmith by Sinclair Lewis

While Pickerbaugh went out campaigning, Martin was in charge of the Department, and he began his reign by getting himself denounced as a tyrant and a radical.

There was no more sanitary and efficient dairy in Iowa than that of old Klopchuk, on the outskirts of Nautilus. It was tiled and drained and excellently lighted; the milking machines were perfect; the bottles were super-boiled; and Klopchuk welcomed inspectors and the tuberculin test. He had fought the dairymen's union and kept his dairy open-shop by paying more than the union scale. Once, when Martin attended a meeting of the Nautilus Central Labor Council as Pickerbaugh's representative, the secretary of the council confessed that there was no plant which they would so like to unionize and which they were so unlikely to unionize as Klopchuk's Dairy.
