Organizational culture is defined as a system of shared meanings held by members that distinguishes an organization. It is shaped by values and behaviors that influence how employees act. There are dominant and sub-cultures within organizations. Culture is created through strategic values determined by management that guide employee actions and behavior. Culture is maintained through employee selection and socialization processes like storytelling that reinforce core values. Organizational change challenges the existing culture and can lead to resistance, so managers must understand reasons for resistance and involve employees in the planning process to successfully implement changes.
