Public relations are entering an era marked by increasing societal dissensus, where shared narratives are breaking down and contentious communication defines the public sphere. This edited volume argues that public relations must move beyond consensus-seeking models to engage with dissent as a critical feature of modern communication. The traditional public relations approaches that pursue collective agreement are increasingly out of step with the contemporary dynamics shaped by political polarization, digital framing, and postmodern challenges to metanarratives. Instead of fighting against the grain, contributors explore how public relations can evolve to effectively function amid conflict, contradiction, and competing values. Various case studies and critical analyses including non-profit organizations, government crisis communication, corporate social advocacy, global diplomacy, and historical movements provide interdisciplinary insights into how public relations can strategically navigate dissents.By repositioning dissensus as a productive condition that requires engagement, this book invites scholars and practitioners to reconsider public relations as a field shaped not solely by consensus but by contestation, complexity, and plurality. As such, this volume offers a timely reevaluation of the public relations field's foundation and future trajectory in a complex world by engaging with dissensus as a site of ethical and strategic potential.
