In most cases, if you do not have a group health policy, or your workforce is not eligible for the same, Employee State Insurance might apply. However, you should be aware of the challenges and advantages of ESI.

Case on Workmen Compensation and ESI Applicability

Source Mobile Pvt. Ltd. is an automobile parts manufacturing firm. It employs a total of 50 workers in a different capacity. Out of this 50, 20 are contract workers, 10 are involved only in clerical jobs or sales functions and do not participate in manufacturing or goods delivery.

Source Mobile has to cover these employees in the following manner:

sales & finance with salary less than rs. 21,000 p.m.8esi@
sales & finance with salary more than rs. 21,000 p.m.2group health policy

@ Health & disability benefits

# Any level of wage. The employer is liable to pay benefits only as per the maximum salary of Rs. 8000 per month, however, may pay a higher compensation, as suitable.

Therefore, it can be said that any medium size or large firm could be eligible for both ESI and WC. However, the major difference is that ESI is an insurance itself, where the employer only needs to pay the premium along with the employee.

Whereas, the WC is pure liability which can be insured under workmen compensation insurance, for which premium is payable by the employer only.

Additionally, the benefits under ESI include healthcare and maternity benefits, which are not part of Workmen Compensation. Workmen compensation only takes care of the income lost due to disability and injury at the workplace, but ESI will take care of health and hospitalization for even unrelated illnesses.
