A labor union is an organization of workers formed to enhance employment conditions through collective action, such as negotiating pay, working hours, and safety standards. From the Industrial Workers of the World’s assertion that unions exist to secure “an adequate wage” and “reasonable hours” to Potter Stewart’s acknowledgment of their role beyond mere job competition, authors have underscored their dual role as practical tools for workers and reflections of broader economic tensions.
Herbert David Croly emphasized unions’ potential to align labor with national interests, while others highlighted their necessity in countering employer influence. These perspectives collectively reveal labor unions as both pragmatic instruments and contested symbols of class struggle.
