This study qualitatively compares how 18 experienced emergency responders from the fire services in Bergen, Norway, and London, United Kingdom, maintained and adapted their organisation's work, routines, and leadership practices to maintain operational capacity, preparedness, and resilience during the COVID-19 (coronavirus disease 2019) pandemic from 2020-23. Semi-structured, qualitative interviews were conducted with nine experienced emergency responders in London and nine in Bergen, enquiring how the pandemic affected their work, their needs for maintaining operational preparedness going forward, and their COVID-19 experiences. Four themes emerged, related to their emotional experiences, how to maintain readiness, continuing to serve the community, and professionalism and learning. The discussion of these themes highlights the need for flexibility in planning, rather than comprehensive plans, and leadership that understands emergency responders' requirements. Drawing on the unique aspects of this study, a two-country comparison and the focus on experienced emergency responders, recommendations are offered for individual and organisational resilience, and the interface between them.
