Values represent basic beliefs about what behaviors or outcomes are preferable. Individuals enter organizations with their own set of values, which influence their attitudes and behavior. Values are learned and passed down through social institutions like family, school, and religion. They help societies adapt through evolutionary or revolutionary change by rewarding behaviors that are gratifying for members. Organizational values also shape individuals over time, as people may conform or leave if their personal values do not align. Peers and colleagues further influence values, as people seek approval. Different occupations develop their own set of values through work and career experiences. Professional codes also establish ethical norms that managers are expected to follow.
