“Lack of awareness: Many citizens are not aware of the existence of a statutory provision that ensures a minimum wage rate. "80% of workers earn less than INR 20/day or less than half of government stipulated minimum wage rate (rural INR 49 and urban INR 67)”.[2] On certain instances of doubt among workers on existence of a minimum wage rate, officials have denied claims of any statutory act or legislation.[11]”
“42% of all wage earners in India receive wages below the national minimum wage floor rate.[62]”
“In Mumbai, as of 2017, the minimum wage was Rs. 348/day for a safai karmachari (sewage cleaner and sweeper), but this was rarely paid.[5]”
