This paper provides a clear understanding of the lived experiences of Healthcare Frontliners during Pandemic Surge. This study utilized qualitative phenomenological research to understand the lived experiences of Healthcare Frontliners during the pandemic surge. The data were obtained through semi-structured interviews with twenty-five (25) questions to discover common themes. Findings show three key themes. Firstly, is Routine Abnormality, where sudden change occurred to frontliners’ routines, resulting in Lack of Sleep, and Change of Lifestyle, causing health risks which impact their performance during work hours. The second theme is Social Responsibility, where frontliners are expected to follow new protocols as Safety Precautions, and to perform their job well as healthcare workers for Fulfilling Duties. The last theme is Motivational Security, as frontliners experience immense stress, they turn to religious and social support as Coping Mechanisms, as well as spending time on hobbies and leisure through Recreation. Healthcare frontliners underwent significant change in their usual lifestyles and had to quickly adapt and use coping mechanisms to help them fulfill their responsibilities while experiencing routine abnormalities. The researchers recommend that the well-being of healthcare professionals be emphasized to ensure a wellfunctioning healthcare service for the community.
