Led by the railroads and the largest industrial corporations such as the Pullman Car Company, Standard Oil, International Harvester, Ford Motor Company and United States Steel, businesses provided numerous services to its employees, including paid vacations, medical benefits, pensions, recreational facilities, sex education and the like. The railroads, in order to provide places for itinerant trainmen to rest, strongly supported YMCA hotels, and built railroad YMCAs. The Pullman Car Company built an entire model town, Pullman, Illinois. The Seaside Institute is an example of a social club built for the particular benefit of women workers. Most of these programs proliferated after World War I—in the 1920s.
