Dorothy worked at a meat packing plant during the 1920s. what would she have been most surprised to see happening at the plant?

Probably the super unsanitary conditions. There was a book written by Upton Sinclair in 1904 about the disgusting and unsanitary conditions of meat factories. Including random and contaminated meats being grinded into sausage along with rat corpses. And employees having no washing stations, so they washed their bloody hands in the water the meat was supposed to be cleaned with.
