If I have correctly understood, you are referring to Zone C, which is categorized for the purpose of payment of minimum wages. Different rates of minimum wages are fixed, keeping in view the cost of living index, with Zone C being the lowest. When it comes to the implementation of existing labor laws, such as PF, ESI, or the Employee's Compensation Act, there is no relaxation. It is to be treated at par with Zone A or Zone B.
I agree with Sh. Saswata Banerjee that the Workman's Compensation Act (now Employee's Compensation Act) is applicable where ESIC is not in existence due to the following reasons:
1. The establishment is in a non-implemented area of the ESI Scheme, or
2. The existing employees are outside the coverage limit of the ESI Act.
