The banking sector is one of the most important economic sectors in the Republic of Croatia. It is significant for the entire functioning of the population and the economy, as well as the entire financial structure. It is particularly sensitive to periods of crisis, which is also evident in the latest COVID-19 crisis. In this paper, research was conducted on the management of the COVID-19 pandemic on the example of OTP bank from the perspective of employees who make up a very significant segment of the banking business. The aim of the work is to analyze the activities of managing the COVID-19 crisis in OTP bank in all phases of the crisis (pre-crisis period, crisis period, post-crisis period), from which three auxiliary objectives arise. Descriptive statistical analysis, correlational statistical analysis and the calculation of the average score for the respondents' attitudes were carried out to achieve the auxiliary objectives of the research. 147 (n) employees of OTP Bank participated in the survey, of which the largest number of respondents were employed in the Department of Business with Citizens, i.e. in the widespread network of OTP Bank branches. The research showed that the employees of OTP bank rated the activities carried out by OTP banka in the COVID-19 crisis as very successful, such as regular notifications about the course of the pandemic crisis, instructions on preventing the spread of the disease and hygiene measures, organizing work from home and other activities. It is evident from the results that they consider activities in the crisis period to be the most successful, while they consider activities in the post-crisis period to be less successful. Correlation analysis determined that the demographic characteristics of employees are not related to the attitudes about the success of the activities of managing the COVID-19 crisis to such an extent, as there are significant correlations between the management activities themselves. This research enriches the literature on crisis management in the banking sector of the Republic of Croatia, but also provides a basis for future research on the relevant topic.
