Final answer:
The method that helps ensure an employee would be free from retribution for reporting fraudulent conduct is whistleblower protection, as supported by various legislative measures.
Step-by-step explanation:
The main answer to the question, which method ensures that an employee would be free from retribution for reporting fraudulent conduct, is whistleblower protection. This method has been established and reinforced over time through legislation such as the Civil Service Reform Act of 1978, the Whistleblower Protection Act of 1989, and the Whistleblower Protection Enhancement Act of 2012. These acts create a legal framework that protects employees from retaliation when they report misconduct or dangers in the workplace, including unsafe working conditions, work-related injuries or illnesses, and policies that may harm the public or employee health and safety.In the context of a compliance program's communication plan, whistleblower protections are essential to encourage transparency and honesty within an organization. Employees need to feel safe and supported when they report any concerns or violations. Measures include the obligation for federal agencies to safeguard employees who come forward and may also involve internal policies of an organization to defend its workers. Ensuring such protections promotes procedural justice and helps avoid negative consequences like workplace violence that may stem from feelings of being treated unfairly or disrespectfully.
