Final answer:
Sharon likely stays at her job because of affective commitment, as she has a genuine emotional attachment to the organization's mission and enjoys her work environment. Her nonprofit could be seen as a normative organization where the reward is more about shared interests and non-material benefits.
Step-by-step explanation:
Sharon, a human resources manager at a nonprofit organization that focuses on sea turtle conservation, most likely stays at her job because of affective commitment. Affective commitment occurs when an employee remains with an organization due to a genuine emotional attachment and identification with the organization's goals and values. Given Sharon's passion for the mission and her happiness in her work environment, it's clear she experiences a personal satisfaction from her job that goes beyond just tangible benefits or a sense of obligation.
Based on sociologist Amitai Etzioni's classification of organizations, the nonprofit where Sharon works could be considered a normative organization, where individuals join out of shared interests and find non-material rewards in being part of such a group. This contrasts with utilitarian organizations, where people join because they receive a tangible benefit, which might not be the primary motivation for those at a nonprofit focused on a cause like saving sea turtles.
