The emergence of the COVID-19 pandemic, with its multidimensional impacts on organisational management, inspired this special issue. The issue presents a collection of full-length articles and research reports devoted to the experiences of enterprises during the first year of the pandemic in various East European countries (Poland, Hungary, the Czech Republic, Russia, Armenia, and Bosnia and Herzegovina).
