Good attempt to describe the welfare measures open to the labor force. However, when you list out the schemes, you should not forget to mention the two basic welfare schemes in the form of social security that are practically available in our country. They are the Employees' Provident Fund, Pension Fund, and Employees' Deposit Linked Insurance Schemes framed under the Employees' Provident Fund and Miscellaneous Provisions Act and the Employees' State Insurance.
There are numerous welfare fund schemes of the state governments that exist only on paper and do not actually benefit the labor class in practice. Some welfare funds require more funding than they receive through subscriptions from employees/employers for administration, payment of salaries and allowances, fees, and traveling expenses of officers. However, the EPF and ESI are the mainstay as the basic social security and welfare schemes available to Indian labor.
