Upton Sinclair's The Jungle in 1906 was a book that shocked the public by exposing the secrets and conditions of the meatpacking houses in Chicago. It worried the public who thought that the wastes of the packinghouse were mixed in with their food. Conditions of the meatpacking houses were exposed when people started visiting the packinghouse to get a feel of what was going on. One of the guides who was assisting the visitors stated "they don't waste anything here. They use everything about the hog except the squeal." (Slaughterhouse Conditions) One thing that stood out to me were the swift workers. Once a task was completed, it was sent to the next person without wasting any time, because they knew that time was money. They had a specialized labor with each person having a specific task that they had to complete.
