 Though the United States steel making industry has gone through a decline through the last half of the 20th Century, U.S. Steel's Fairfield Works continues to be a major employer, though not in the levels seen around the 1950s.Advances in steel-making technology have enabled the works to produce roughly the same amount of product as during that era, but with a much smaller workforce.Portions of the Works have been closed over the years, but many parts of the complex have been reopened by smaller industries, some of which are steel-related.
