The characteristics and values of an organizational culture are shaped under the influence of the macroculture in which that organization has been developed. Macrocultural characteristics can be identified through cultural dimensions of national culture, whereby we define culture as an orientation system that unconsciously affects our behavior and the way we perceive the immediate environment and the world that surrounds us. The development of an organizational culture will therefore be unconsciously influenced by values of a certain national culture, while the characteristics, agreed values and acceptable behaviors will initially be consciously shaped by the founder of the organization and they will be transmitted throughout the organization through the processes of socialization and behavior of leaders in the organization. This paper will provide a theoretical basis for understanding the concepts of organizational culture, employee development and national cultural dimensions and aims to determine whether there is a link between the characteristics of the Croatian macroculture, that is, the Croatian national cultural dimensions and the characteristics of the organizational culture of Addiko Bank. If the link exists, it signals that certain national cultures shape certain organizational cultures, regardless of the activities the organization is engaged in. With the aim of determining the link between the characteristics of the Croatian macroculture and the organizational culture of Addiko bank, an analysis of the organizational culture of Addiko bank is carried out and an answer is given to the question of whether it contains characteristics that directly positively affect the development of employees. Through a comprehensive analysis based on direct observation and guided by Edgar Schein's theory, through the application of Geert Hofstede's theory of cultural dimensions and conducting a survey of Addiko Bank managers, the aim is to come to the conclusion whether certain characteristics of the macroculture are reflected in the values of the organizational culture and, if so, which and whether they are influenced by the resulting specifics of organizational culture on employee development. The aim of the paper is to identify the values of Addiko Bank's organizational culture based on the Croatian macroculture, which positively influence the equal and inclusive development of all employees, regardless of cultural affiliation, age, gender, so that this knowledge can be used to develop similar characteristics of organizational cultures of other organizations.
