In an editorial, former U.S. Congressman David Bonior and Wayne State University labor studies professor, wrote that employers are increasingly using aggressive methods to exploit already-weak labor laws. When faced with organizing drives, 30 percent of employers fire pro-union workers, 49 percent threaten to close a work-site if the union wins, and 51 percent coerce workers into opposing unions with bribery or favoritism. Bonior wrote that American workers "have the fundamental human right to collectively bargain. We must support the freedom to climb the ladder to the middle class via unions."
