This Undergraduate Thesis explores the key aspects of organizational climate and its impact on the efficiency and success of the organization. Organizational climate refers to an employee's perception of the work environment, including factors such as management support, communication, and interpersonal relationships. Organizational culture, on the other hand, encompasses the more deeply rooted values, beliefs, and norms that shape behavior within an organization. The research on the organizational climate was conducted through a questionnaire in which specific aspects of the organizational climate in the selected organization - Zagreb public relations agency are examined. The aim of the research was to analyze certain aspects of the organizational climate, i.e. corporate communication, work organization, dedication to work, inter-personal relationships, working conditions and emotional support in the selected public relations agency. A significant number of respondents answered that corporate communication con-tributes to their sense of belonging in the company. Most employees answer that they are satisfied with the organization of work. Almost all employees answer that they are willing to put in extra effort for the company's success, which proves their commitment to work. They believe that there is a good working atmosphere in the company and are satisfied with interpersonal relationships, where teamwork is especially emphasized. A slight deviation was found in working conditions, although most employees are satisfied with the same. As far as emotional support is concerned, the results indicate very positive statements in which the satisfaction of emotional support at work is expressed. The results of the research showed a generally positive perception of the organizational climate.
