The COVID-19 pandemic is a challenging situation both for the general population and for health employees. This unprecedented public health crisis caused by the SARS-CoV-2 virus has a great psychological impact on healthcare workers on the front line of defense and as such represents a great threat to their health and professional ability. The aim of the research was to directly examine the state of mental health of healthcare workers to the COVID-19 pandemic and to determine the factors that affect mental health and satisfaction at the workplace during the COVID pandemic. The study involved a total of 207 nurses / technicians aged 18 to 55 years, average age 34.18 +/- 7.76 years, length of service from less than one year to 35 years, average length of 13.56 +/- 8.76 years of service. A questionnaire for nurses / technicians was created, which consisted of questions about the socio-demographic characteristics of research participants (age, gender, completed education, length of service). One part of the questionnaire examined the way nurses / technicians work (shifts, how they got to work in the COVID department, time spent working in the COVID department). The questionnaire also contained several questions about their subjective impression of their own capacities and environment during work, as well as questions related to direct work at the COVID department. Two hypothesis-related questionnaires measured satisfaction with workplace conditions at the time of the COVID-19 disease pandemic and the degree of burnout and exhaustion in the past year. The IBM SPSS 23 program was used for processing. The results were coded and analyzed and also descriptive results are presented in frequencies and percentages, arithmetic mean with standard deviation with the range of results and the Cronbach alpha coefficient as a measure of inner reliability. Hypotheses were tested with Pearson's and Spearman's correlation. Nurses and technicians are mostly not satisfied with the working conditions and the organization of work at COVID departments. The statistical indicator is also a significant negative connection between exhaustion and satisfaction of nurses/technicians. The more the symptoms of burnout at work are shown and the more the workers are in the condition prolonged physical and mental exhaustion, the more dissatisfied they are.
