The environment of public relations practice in Nigeria features dynamics that do not exist under the scholarship radar yet and need to be explored to enhance the profession. This study investigated how the employer, client, colleague, society, and professional association influenced the professional values of public relations practice among practitioners in Lagos State, Nigeria. Based on a survey design, it turned out that these factors collectively influenced the values, thereby eliciting new responsibilities on how the environment shapes public relations. It also indicated the need for the Nigerian Institute of Public Relations and other relevant bodies to escalate their training of both the members and staff to keep up with the new responsibilities.
