The global pandemic of corona virus (COVID-19) began in 2019 in China. COVID-19 is an infectious, contagious disease that rapidly spread throughout China, and soon to most countries around the world. The disease was transmitted by droplets - through coughing and respiratory tract, but also through contaminated surfaces and the spread of aerosols. Given that the COVID-19 pandemic took on global proportions and had a high percentage of patients in a very short time, there was a need for a much larger volume of medical care. Due to the rapid spread of infection and insufficient knowledge of the ways and reasons for the spread of this disease, as well as the serious health consequences that this disease can cause, the fear of infection and the fear of the consequences of infection soon spread. The medical staff was the most under attack because the volume of work increased significantly, and the working conditions were not adequately adapted to the new situation. Due to the sudden increase in the volume of work and the extremely rapid spread of the COVID-19 virus, there was a lack of adequate employee education, adequate organization of work and working hours. Given the continuous exposure to the virus at random places, and the increased number of working hours and duties, medical workers were exposed to many stressors at random places. In this paper, research was conducted on the dissatisfaction of medical workers in the area of the city of Pula during the COVID-19 pandemic. Exposure to numerous stressors in the mentioned period resulted in an acute stress reactions and disorders in the mental and physical condition of healthcare workers. For medical workers, it becomes more and more difficult to adapt to new changes and new working conditions. Dissatisfaction grew and negative emotions become more pronounced, which often led to mental and physical illnesses of medical workers.
