Republican governors in southern states are pushing back against United Auto Workers' effort to organize automotive factories. 

South Carolina Gov. Henry McMaster is among those saying unions could lead to layoffs and fewer investments. 

"The reason why the latest effort is happening is largely because of the success that the UAW had with its strike last year against General Motors, Ford and Stellantis," Steven Sylvia, professor at American University, said on WCNC's Flashpoint.
