What were northern factory workers called in the US?

Northern factory workers in the U.S. during the 19th century were often referred to as "wage laborers" or simply "workers." Many were part of the burgeoning industrial workforce, particularly in cities like Lowell, Massachusetts, and Pittsburgh, Pennsylvania. They played a crucial role in the Industrial Revolution, contributing to the growth of industries such as textiles and steel. Over time, some organized into labor unions to advocate for better working conditions and wages.
