Americans have worked just about everywhere:
Where we worked affected when we worked, with whom we worked, and the nature of that work. For example, in 1870 only a handful of factories employed over 500 workers. By 1900, 1,063 factories employed between 500 and 1,000 people. During the first half of the 20th century, many African American women worked as domestics in private homes, but during World War II, they took advantage of new opportunities at shipyards and factories.
By the end of the 20th century, a dramatic shift took place, sending individuals who had worked in factories, plants, and mills into jobs in offices, stores, and restaurants.
Photographers have always been inspired by worksites. The camera can capture the size and power of the factory, the speed of the assembly line, the dark of the mine, and the close confines of the cubicle.
