The COVID-19 pandemic has brought numerous changes in the field of education, especially in the form of the work of school staff, and this includes the Croatian context. The aim of this paper is to provide insight into the factors that helped or hindered the employees of one high school in achieving the organizational resilience of their school during the pandemic. Following a literature review of the impact of the pandemic on the work of schools around the world the paper presents the qualitative research it is based on. Five semi-structured interviews werecarried out with employees of the selected school about their experience of work during the pandemic. These included the principal, two teachers, a pedagogue and a member of the school’s support staff, in order to gain insight into the functioning of the school during the pandemic. The theoretical review identified the main dimensions through which the organizational resilience/vulnerability of the school was explored from the perspective of its employees. These identified aspects were: potential changes in the structure and management of the school. Also, availability and quality of equipment and technology that the school had at its disposal during the pandemic. Furthermore, the quality of cooperation and communication was explored. Also, the focus was placed on external support networks that enabled the functioning of the school. The results of the level of organizational resilience of the school are observed from the previously described dimensions, suggesting that the explored school had a high degree of organizational resilience during the pandemic. Namely, financed from various sources, it had enough equipment and technology to hold classes in digital reality. Also, the joint decision-making related to the organization of school and teaching process and the high level of support and exchange of knowledge among employees, as well as the successful management of the school and the close relationship between the school and the local community in which it is located, were evidence of a high level of organizational resilience. The last chapter of the paper is devoted to recommendations for developing various aspects of organizational resilience within the school during crisis situations such as the COVID-19 pandemic.
