Final answer:
Catherine is displaying Organizational Citizenship Behavior (OCB) by going beyond her job duties to pick up trash in the parking lot, a voluntary and beneficial action for the organization.
Step-by-step explanation:
Catherine, by picking up the trash she found in the parking lot, is exhibiting what is known as Organizational Citizenship Behavior (OCB). OCB refers to voluntary behaviors employees perform that go beyond their normal job expectations and contribute positively to the organization. These actions are not formally rewarded or recognized by the formal reward system but can contribute to a more efficient and effective work environment.
OCB is distinct from other behaviors because it is discretionary and typically benefits the organization or its members. Catherine's action is a small but meaningful example of OCB, reflecting a personal commitment to contributing positively to her work environment, even in ways not outlined in her job description.
