Which of the following describes actions forbidden for personnel decision-makers?

The correct answer is particularly focused on the concept of Prohibited Personnel Practices. These practices detail specific actions that are forbidden for personnel decision-makers in order to uphold fairness and integrity within the hiring and employment process. They address concerns like discrimination, nepotism, and retaliation against whistleblowers, ensuring that decisions related to hiring, promotion, and other employment practices adhere to established regulations designed to protect employees and job applicants.

By adhering to the principles laid out in the prohibited personnel practices, decision-makers help maintain a merit-based system where qualifications and performance are the primary criteria for employment actions, rather than personal biases or improper influences. This is crucial not only for compliance with legal standards but also for fostering a positive workplace environment.

While the other options might represent various frameworks or guidelines related to employment processes—such as merit systems or administrative procedures—they do not specifically encapsulate the actions that are deemed forbidden for personnel decision-makers. The focus on prohibited personnel practices is essential for ensuring ethical conduct and equal opportunity in federal employment.
