The COVID-19 pandemic revealed and exacerbated migrant workers' vulnerabilities in India, resulting in widespread unemployment, displacement, and social unrest. Migrant workers still have to deal with a number of issues even after the epidemic, including precarious employment, pay loss, a lack of social protection, subpar housing circumstances, and restricted access to assistance and healthcare facilities. This study looks at the socioeconomic and psychological effects of migrant workers' post-COVID-19 struggles. The implications for social work practice in addressing these problems through advocacy, intervention, and rehabilitation techniques are also examined. Lockdowns and the slowdown in the economy severely disrupted the livelihoods of migrant workers, who are the backbone of the informal economy. Many went back to their home countries without sufficient support networks, and they now have trouble reintegrating and finding steady work. The study highlights the necessity of inclusive welfare programs, robust policy frameworks, and efficient implementation strategies. Through counseling, community organizing, raising awareness, and connecting migrant communities with government services, social workers play a critical role in empowering these people.
