If the workmen are working in non-implemented areas of ESI, cover them under WC / Employees' Compensation Policy. Under this policy, there is also a provision for hospitalization claims due to accidents up to Rs. 1 lakh with some additional premium.
Additional Term Life Insurance
Additional Term Life Insurance cover is the best option for workmen. This policy provides cover for any kind of death due to accidental or natural causes anywhere in India with a nominal premium for Group Coverage.
Group Mediclaim Policy
Introduce a contributory Group Mediclaim Policy for workmen with a reasonable premium deductible from wages and share the employer's contribution equivalent to 4.75% for this policy.
If you have a large number of workmen, you can negotiate with insurance companies and reduce the annual premium drastically, at least for the first year, and thereafter depending upon the claim ratio.
