The topic of ethical conduct in public administration communication is a current concern, in the context of rapidly evolving technological developments and the proliferation of digital media platforms. It can guarantee the honesty, openness, credibility, and responsibility of public institutions. Public communication has the power to shape public opinion, influence behavior, and impact society at large. Ethical communication practices consider the broader social consequences of messages and strive to promote the public good rather than personal gain or organizational interests. The study employs a comprehensive analysis of the literature review in this field. In this regard, this chapter aims to understand the ethical framework and to identify ethical issues in public communication. A key case study examined is the Roșia Montană Gold Corporation controversy, which serves as an illustrative example of ethical dilemmas in corporate communication, public relations strategies, and civil society responses. The findings underscore the significant impact of digital media and social networking platforms in disseminating information. Social media platforms like Facebook, X (former Twitter), and YouTube have become important channels for public administration communication, activism, and citizen engagement, but they also pose challenges related to misinformation, hate speech, and online manipulation. The implications of this study extend beyond the borders of Romania, offering insights regarding the promotion of social responsibility, mitigating harm, enhancing professionalism, and building sustainable relationships.
