Corporate Culture is a concept that encompasses a group of beliefs, expectations and values embraced by a majority of employees in a company and represents a system of values expressing the philosophy, vision and mission of an organization. It manifests itself through company’s symbols, language, decor and iconography. Corporate culture includes basic assumptions and beliefs about reality, truth, time and space on the one hand, as well as the assumptions about human nature, activities and relations on the other. It manifests itself in the language used by an organization, in the organization’s stories and rituals. In a broader sense, it influences the employees’ motivation, as well as the management of human resources. Corporate culture likewise influences the selection of employees. No corporate culture is a monolithic culture – it is a product of a complex system of subcultures, with all their respective characteristics. There is a vast difference between strong and weak cultures, and this is reflected in the level of success of a given company. Corporate culture can be strongly influenced by a national culture, but it can also considerably differ from the culture that surrounds it – and this state of affairs in the long term inexorably leads to conflicting situations. It is based on a learning organization and it determines the type of the organizational structure and management style. Corporate culture can also be perceived as a driving force of an organization in view of the fact that it instigates or determines a harmonious, unidirectional engagement of the employees. The concept of corporate culture is especially important when attempting a significant organizational change. Organizational changes have to include not only structural changes, but the change of a corporate culture as well. Successful changes in business are not possible without a change of corporate culture. In hotel management, corporate culture develops according to its specific circumstances and a number of hotels or even hotel corporations are influenced by the authoritative vision of important hoteliers, who created a corporate culture by the force of their personality. Corporate culture represents a decisive element of difference. This assumption is especially prominent in the case of hotel brands and in the case of independent hotels with an exceptionally strong corporate culture. Corporate culture manifests itself in employees’ behavior, their attitude towards guests, their participation in humanitarian activities, the company’s care for its employees and so on. Hotel categorization and classification are also important elements of corporate culture, whether in terms of the category (the number of stars), or in terms of a hotel’s profile (sea resorts, city hotels etc.). The examination of the hotel chains’ corporate cultures reveals the importance of the choice and the implementation of a corporate culture, which is occasionally determined by various factors - including the owner’s origins, family habits, religious beliefs etc. An analysis of the corporate culture of hotel associations reveals the similarities and differences of the systems whose members are not strictly associated with them, but which have a recognizable corporate culture nevertheless. Research done on hotel corporations reveals that a strong corporate culture ensues from continuous training and that it strongly influences the behavior of employees towards guests and their attitude towards the employer. Research also shows that the change of ownership of a hotel does not necessarily entail a drastic change of the corporate culture - if the culture is strong. In that case, the role of the manager is of the utmost importance. Certain hotel chains, which boast a strong corporate culture, founded their own educational centers in order to reach, maintain and improve a high level of quality – a process in which corporate culture is of the utmost importance. Corporate culture is an exceptionally important factor of successful hotel management considering the fact that it represents a competitive advantage and in the end influences profits. One of the principal tasks of big hotel corporations is therefore the development and maintenance of their corporate culture.
