Answer:
politicking
Explanation:
In sociology and management, politicking refers to using someone's power to benefit an individual or organization. This benefit is carried out regardless of the organization's best interest or principles.
In this case, Marilyn is abusing of her power as department head to help Nick, whose job evaluations are favored for being Marilyn's protegee. The fact that she eliminates all the client's that Nick couldn't handle properly favors him unfairly and hurts the organization. Nick is being awarded a raise and possibly other benefits while his job is not that good and he probably wouldn't deserve it, not obtain it if someone else was his manager.
