The three basic elements of an organization are culture, structure and individual members, whereas the organization is influenced by the environment, society, aims and history of the organization. Not only does it influence the employee’s acceptance of organizational changes, organizational culture can also affect the creation of organizational commitment, organizational trust and positive attitude. Culture is important for an organization because it defines most of what is being done and how it is done in the organization. Once established, cultural organization influences the members of the organization and significantly determines their behavior. Human resource development should work at all levels and it is directed toward all the structures in the company (managers and employees). The aim is to respond to the environment, i.e. to react in the best possible way to the changes that come from the environment. Every career has its own development phase. The most commonly spoken about is the initial phase, the advanced phase, the middle phase and the late phase.
