The movement to implement “right-to-work” (RTW) legislation has accelerated over recent years. Since 2012, RTW laws have been passed in Indiana, Michigan, Wisconsin, West Virginia, Kentucky, and Missouri. This report investigates the impact of RTW laws passed in three Midwest states for which there is available data – Indiana, Michigan, and Wisconsin – compared to a control group of three Midwest counterparts that remained collective-bargaining (CB) states – Illinois, Minnesota, and Ohio – from January 2010 through December 2016.
