The imposition of lockdowns in several nations has resulted in restricted movement of an individual, leading to a mobility crisis in India. As migrant labourers strived to make their way back home, it led to certain confrontations with relief policies, law enforcement, and transit policies being enforced. Interstate migrant workers in India have been facing a myriad of challenges in this accord and are predominantly engulfed with sociological, psychological, economic, political, and legal dimensions. This research article examines their pre- and post-COVID-19 living and working conditions, focusing on the diverse migrant population residing in Kelakottaiyur. The objective of this study is to understand the working and living conditions of the migrants in correspondence with the diversity prevailing within. It can be further validated in terms of employing a convenience sampling method in juxtaposing potential selection bias and self-reporting (or) recall bias. According to the findings of the study, the circumstances under which migrant labourers work have a significant impact on their overall quality of life. Specifically, their living conditions, job satisfaction, and socio-economic status are all prejudiced by the nature of their employment. This study aims to prove that Interstate migrant workers in India are vulnerable in terms of mobility, health, and well-being, by elucidating a comparative analysis between their respective professions and livelihood, during the Pre- and Post-COVID-19. Furthermore, it underscores the importance of creating fair and supportive working environments for all individuals, regardless of their background or status.
