As companies increasingly engage in controversial social issues, corporate social advocacy (CSA) has become a prominent yet often contested form of corporate communication. This talk explores how publics respond to CSA across contexts, while also examining how such engagement is understood and managed within organizations. It discusses how support and opposition emerge in social media environments, reflecting broader dynamics of political consumerism in response to corporate stances. The seminar further considers key antecedents shaping public responses, including organizational-public relationships, political affiliation, and belief alignment in influencing legitimacy perceptions. Complementing these perspectives, interviews with communication professionals highlight the organizational challenges and strategic considerations involved in practicing CSA. Together, these insights offer a comprehensive view of the dynamics underlying public responses and organizational approaches to corporate engagement in sociopolitical issues.
