For those unaware. The Pullman Company (also known as the Pullman Palace Car Company) was a massive company on the south side of Chicago that was founded in 1862 by George M. Pullman. Pullman built railroad passenger cars (and later freight cars) and staffed them with their own porters. The level of craftsmanship and service on the cars became the national standard of 1st Class service on passenger trains during the golden age of rail travel. Traveling in “Pullman Service” was the top tier of domestic travel before the advent of major commercial aviation. The cars were so well built that there several100+ year old cars built by Pullman still in private charter service. Many more are preserved (in operating condition) in railroad museums across the US.
A unusual circumstance of employment at Pullman was that employees had to live in the company owned city that was built around the gigantic factory.
George Pullman has been simultaneously considered one of the greatest and worst industrialist in American history. His willingness to hire black Americans and immigrants in large numbers being one of his virtues. The requirement of living in Pullman was not. Things eventually fell apart with employees being forced to live in Pullman homes where they had to pay rent to the company. When wages were cut by 25%, and rent was not, it triggered one the largest industrial strikes in US history.
The Pullman strike of 1894 disrupted trade in the United States to the point that President Grover Cleveland had to intervene. A result of this strike (amongst many labor related things for the workers) was the creation of the national holiday, Labor Day and the concept of weekends.
Pullman went bankrupt and ceased operations in the 1980s. The last railroad cars they built were the Superliners Is for Amtrak. Many of the cars and the very last production car are still in operation. You may see it on the rails. Car #32009 is a sleeping car, and in the tradition of sleeping cars having unique names, is named George M. Pullman.
The former Pullman factory site is now a National Landmark (thanks, Obama) and is absolutely worth visiting if you're in the Chicago area.

Remember some of this when your employer tries to tell how you don't need a union. It CAN be much, much, worse for workers if corporations have their way.
