This research Paper is based on the objective of critically analysing the welfare schemes running for casual labourers in India. Casual Labourers comes from the informal sector of the economy and they do not have much required social security. They face lot of problems like low wages, long working hours, miserable working conditions, poor quality of life, low access to health, education and other basic facilities like housing, clean drinking water, good quality of food etc. In order to help them, many social security schemes are running in the country. Among them major ones are Pradhan Mantri Jeewan Jyoti Beema Yojana (PMJJBY), Pradhan Mantri Suraksha Bima Yojana (PMSBY), Ayushman Bharat, Pradhan Mantri Shram Yogi Maan Dhan (PM-SYM) Pension Scheme, One Nation One Ration Card, Mahatma Gandhi National Rural Employment Guarantee Act, Pradhan Mantri Awas Yojana, Pradhan Mantri Kaushal Vikas Yojana. Their knowledge about the welfare schemes is very low due to lack of awareness and illiteracy. Hence, being in a situation of dilemma, they are unable to take the benefits of the welfare schemes properly. This research paper aims at the critical review of these schemes and also focuses on finding the difficulties faced by casual labourers in achieving the benefits of these schemes, with the help of interview schedule method by taking interview of 100 workers of Kanpur Nagar. The major findings include improper implementation of welfare schemes due to corruption in some cases and poor execution of the objectives of the schemes at grass root level. Casual labourers also find it very difficult to understand properly about all the objectives of the schemes as they are not aware of the rules and regulations about a particular scheme. It seems that awareness campaigns, easy rules of execution of the schemes and regular quality check is required to make things better.
