Leaders consciously or unconsciously use techniques to gain power and authority. Leaders are people who have innate abilities to influence others. They improve their abilities and do not keep their knowledge to themselves, but gladly share it with others because they are aware of how important it is to have quality and professional staff. Leadership techniques for achieving power and authority are often the subject of discussion by many authors, scientists, professionals and others who seek to present the key to achieving power and authority by implementing leadership techniques in business. A leader should strive to develop his or her ability to influence others and achieve a high level of authority that is solid and consistent so that his or her employees or subordinates carry out given orders and implement decisions and contribute to the improvement of organizations. There are several situations from which power and authority arise, but also through techniques by which a leader can continuously maintain and increase his position of power and authority. During the research of the thesis topic, and with the aim of better preparation, various scientific, written and digital works, professional journals, and Internet portals dealing with the topic of leadership techniques, power, authority, influence, position, and the like were studied. The aim of the paper is to present the findings of the paper, related to the theoretical processing of concepts and previous research in the field of work and conduct research to conclude on which leadership techniques contribute to achieving power and authority, but also to determine the interdependence of leadership elements that synergistically affect business performance. The research was conducted in eight companies, organizations and institutions from different industries, such as: Boso d.o.o., Cestorad d.d., Grad Vinkovci, Grad-Export d.o.o., Iver d.o.o., Ivan Mažuranić Elementary School Vinkovci, PTUO ŽRVANJ and Vinkoprom d.o.o. Business owners and employees who answered different but related questions were surveyed so that their answers could clash with the goal of identifying leadership techniques by which leaders achieve power and authority. Surveyed leaders and employees confirm scientific research on those leadership traits that are key to good leadership. Respondents confirm the harmony of leadership elements and company performance. The importance of communication and delegation of work and the strong leadership of leaders as the foundation of the organization can be determined.
