This paper examines the changing dynamics of labour of the Ex- Tea garden tribe from the Tea garden tribe in the Sonitpur District of Assam. Hence, factors such as migration or labour mobility, social, economic, cultural, and political aspects have been taken into account for understanding the socio-economic contribution of the Ex-Tea garden tribe labour population in the region. The paper also argues that Ex- Tea garden tribe labour despite their distinct identity and socio-economic contribution to the region is overlooked in different aspects of society in the region. This endangers the growth and development of Ex- Tea garden tribe labour community in various fields in the Sonitpur District of Assam.
