The pandemic process has caused many difficulties, both economically and psychologically. The spread of the virus worldwide has caused millions of people to be infected. The rapid spread of the pandemic forced states to take urgent measures. Radical measures such as curfews, mask and distance rules, closures, and travel restrictions have caused a difficult process for both people and businesses. The news of death caused by the virus in the media increased people's fear and anxiety. The unique rules of the new normal process that entered human life with the pandemic also affected the shopping habits and purchasing behaviours of people who are ultimate consumers. Adapting to the changing process and differentiating consumer behaviours has become a necessity for businesses against entropy. The departing of qualified personnel from the sector has resulted in businesses having a problem with human sources. In addition, the need for leaders has emerged for businesses, who will adapt themselves to the new process, motivate human resources, structure the production and marketing infrastructure according to the new normal process, and analyze the current and future trends. It has become important to establish close relations with employees considering their health sensitivity. In this study, the types of leadership that can adapt businesses to the new process are considered transactional leadership and transformational leadership. The study, which analyzes both types of leadership in detail, is expected to contribute to both the literature and the field of practice. In addition, it fills the gap in the literature in terms of the leadership in the pandemic process and is original.
