Redneck has labor roots, people like Michael Moore explain this in his documentary Fahrenheit 11/9. People have forgotten this history. The term "redneck" has multiple origins, but one significant historical source comes from coal miners in West Virginia during the Battle of Blair Mountain in 1921. Union coal miners wore red bandanas around their necks as a symbol of solidarity and collective action during their struggle against mine owners who exploited their labor. This protest, known as the Battle of Blair Mountain, was one of the largest labor uprisings in U.S. history, and the red bandanas they wore earned them the nickname "rednecks."

This was beautifully expressed in the West Virginia teachers strike a few years back: https://youtu.be/JEjU-X57Wrc?t=4313
