The National Right to Work Foundation said Tuesday that Dennis Murray and Cynthia Ramaker had filed an appeal with the National Labor Relations Board.
Murray and Ramaker initially filed a complaint in December, saying the Machinists had retaliated against workers at the non-union plant in North Charleston. The NLRB dismissed that complaint in July.
Last year, the NLRB dropped a lawsuit against Boeing after the Machinists approved a four-year contract extension with the aircraft manufacturer. The NLRB lawsuit said Boeing broke labor laws when it opened a North Charleston production line, punishing unionized workers in Washington state for past strikes.
Boeing said it needed the South Carolina plant for valid economic reasons.
