Not Following Employees’ State Insurance Act, 1948 & Workmen's Compensation Act, 1923

Dear HR Professionals,
We are having family health insurance from private insurance company for our all employees. But we are not following Employees’ State Insurance Act, 1948 & Workmen's Compensation Act, 1923.
Is it legal or illegal?
Please clarify above things
Thanks with Regards

If you have 10 employees you should have ESI registration. It is mandatory and you cannot replace it by any medical insurance. Moreover, no insurance company has ever given any benefits to insurer for his existing disease. No insurer will cover your parents aged more than 70 or 80 or even 100 years. But ESI Corporation does it.
Nothing is going to happen if you do not have any Workmen's Compensation Policy until any major accident or death during the course of employment happens. Noting will happen if your employer is able to pay the compensation for death or total disability from his pocket.
In respect of employees covered under the ESI, separate Workmen's Compensation policy to cover the above risk is not required.
