Final answer:
True, withholding a raise from a subordinate for refusing to date the supervisor is an example of quid pro quo harassment, which is a form of sexual harassment involving the conditioning of employment benefits on sexual favors.
Step-by-step explanation:
A supervisor who withholds a raise from a subordinate who refuses to date her is indeed an example of quid pro quo harassment. This form of sexual harassment involves an exchange where work-related benefits are conditioned on sexual favors. If such benefits are denied because a sexual advance or request is rebuffed, it meets the criteria for quid pro quo harassment. This is just one aspect of inappropriate workplace behavior, with the other being a hostile work environment characterized by an intimidating, offensive, or oppressive atmosphere created by repeated sexually-based behaviors.
