Union members report equal levels of satisfaction with their labor organizations whether they are in states with a right-to-work law or without one, with workers in right-to-work states expressing slightly higher levels of satisfaction with their union in some cases, according to a new study.

“The data … suggests that there is no appreciable difference between union employees from union and right-to-work states and that union employees in right-to-work states are not inadvertently suffering from the prohibition of union security agreements. There is also significant interest among union employees in all states in certain labor law reforms that would give them greater ability to select their representation,” according to a study released Monday by Lloyd Corder, an adjunct professor at Carnegie Mellon’s Tepper School of Business. The study was commissioned by National Employee Freedom Week, an advocacy group that promotes right-to-work laws.
