The COVID-19 pandemic has affected Bangladesh's economic and social well-being in many ways. During the lockdown, many households lost their full income. The day labors and the slum dwellers including rickshaw pullers, CNG drivers, housemaids, hawkers, and street vendors were the worst victims of this pandemic. Besides the voluntary organizations, the city corporation, being instructed by the central government took the initiative to distribute necessary food as well as financial assistance to the city dwellers to survive during the lockdown. The objective of this study is to identify the satisfaction level of the slum dwellers with the assistance received from the City Corporation and get an idea of how far these supports were enough for them to lead their livelihood. It is a mixed-method research consisting of both qualitative and quantitative approaches. Researchers conducted a field survey in Sylhet City Corporation, the northeastern part of Bangladesh, and collected primary data from eighty respondents through a semi-structured questionnaire along with an interview schedule. Samples have been selected by applying a multistage sampling technique. Researchers analyzed quantitative data using SPSS software and qualitative data using the thematic analysis method. Study findings reveal that, although this aid was very inadequate compared to the needs of the slum dwellers, it was able to alleviate food shortages to some extent in times of extreme hardship. However, some dwellers got deprived of the aid due to having different political ideologies and corruption. Proper aid management, well coordination, and community participation are indispensable for dealing with any crisis.
