Final answer:
True, plagiarism in public speaking can cause both public humiliation and loss of a job, as it is a serious ethical violation that can damage professional reputation and trust.
Step-by-step explanation:
True, plagiarism in public speaking can indeed lead to public humiliation and the loss of a job. Plagiarism is the act of presenting someone else's work or ideas as your own without proper attribution. This practice undermines trust, and suggests a lack of integrity, and in professional or academic contexts, it is viewed as a serious ethical violation. The consequences of plagiarism extend beyond personal embarrassment; they may include damages to one's professional reputation, legal repercussions, and the potential for loss of employment, particularly if the plagiarized speech is integral to the person's job or public persona. It is not only about avoiding public humiliation but also about maintaining ethical standards and trustworthiness. Given the importance of originality and honesty in professional settings, individuals engaging in public speaking should make a concerted effort to provide ethical attribution and avoid plagiarism to prevent these severe outcomes.
