Final Answer:
For detailed definitions of the full range of retaliatory behaviors, refer to D. The applicable policy or regulation.
Step-by-step explanation:
In matters of workplace conduct, the detailed definitions and guidelines regarding retaliatory behaviors are typically outlined in specific policies or regulations established by the organization. These policies are designed to provide employees with clear information on prohibited actions and the consequences of engaging in retaliatory behaviors. Options A and B, the Employee Handbook and the Code of Conduct, may contain general information on workplace behaviors but may not provide the comprehensive details needed for specific definitions of retaliatory actions.
Option C, the Whistleblower Protection Act, is a federal law in the United States that protects whistleblowers from retaliation but may not necessarily provide detailed definitions of various retaliatory behaviors. Therefore, the most appropriate source for detailed definitions would be the applicable policy or regulation established by the organization.
Option D is the answer.
