The first edition of Why Unions Matter was published in 1998. In it I argued that unions mattered because they were the one institution that had dramatically improved the lives of the majority of the people and had the potential to radically transform both the economic and political landscape, making both more democratic and egalitarian. I showed with clear and decisive data that union members enjoyed significant advantages over nonunion workers: higher wages, more and better benefits, better access to many kinds of leaves of absence, a democratic voice in their workplaces, and a better understanding of their political and legal rights. What is more, unions benefitted nonunion workers through their political agitations and through what is called the "spillover" effect—nonunion employers will treat their employees better if only to avoid unionization.
