Organizational culture is defined as a set of values, norms, symbols and behavior patterns shared among employees. Organizational culture is explained within the framework of Edgar Schein's three-layered model (visible structures, espoused values and basic assumptions). It is emphasized that this culture is determinant in many areas from decision-making processes in the organization to leadership styles, conflict management and openness to change. Organizational ethics, on the other hand, is considered as a set of values that enables the evaluation of right and wrong, fair and unfair at the institutional level. Ethical principles (honesty, justice, responsibility, transparency, etc.) are at the basis of organizational decisions and shape the relationship of the organization with both internal stakeholders (employees, managers) and external stakeholders (customers, society).

In the reciprocal relationship between organizational culture and ethics, it is stated that a strong organizational culture can support ethical behaviors while a weak or corrupt culture can prepare the ground for unethical practices . In this context, it is stated that ethical leadership, written ethical codes and ethical climate play a critical role in the formation and maintenance of organizational ethical awareness.

In this chapter, the concepts of organizational culture , which is one of the basic building blocks of organizations, and organizational ethics, which has become an indispensable element of corporate life, are discussed. The chapter focuses on the definitions, theoretical foundations and practical implications of both concepts, and reveals how these two structures are intertwined in terms of the functioning and sustainability of organizations. It is stated that an organizational culture based on ethical values increases employee loyalty, strengthens corporate reputation and contributes to sustainable success in the long run. In this framework, it is emphasized that organizations should adopt not only performance and result-oriented but also value-oriented management approaches.
