Final answer:
Bettina Samuels is considered a whistle-blower for resorting to the media and the federal government regarding her company's unethical environmental practices.
Step-by-step explanation:
Bettina Samuels would be considered a whistle-blower because she resorted to the media and the federal government to address the grievance. By alerting external parties, such as the media and the Environmental Protection Agency (EPA), she disclosed unethical and possibly illegal practices of her employer that affected the environment. This aligns with policies and protections put in place to encourage individuals to speak out against wrongdoing, without fear of reprisal, as indicated by the Civil Service Reform Act of 1978, the Whistleblower Protection Act of 1989, and the Whistleblower Protection Enhancement Act of 2012.
