Hi Kumarvipin,
I agree with the wise comments made by Mr. Dahiya and Mr. Sharma.
Even if you take a corporate insurance policy, you cannot get exemption from ESIC, if your establishment and employees are within the ambit of the Act.
I can tell you from practical experience that we tried this out in one of the company I worked with way back in year 1998 - 2004. The company took medical insurance and applied for exemption from ESIC. The ESIC as expected rejected the application. The company contested it. The case took nearly 6 years and eventually the company had to pay the ESI dues with interest and penalty and I must say it added up to a 'huge' amount and the liability reflected in the Balance Sheet and a whole lot of effort was needed to get through the process and eventually close it. The cost and the executive time + legal time we spent on it was not worth a single penny that we spent on this whole exercise.
So, my suggestion is - avoid the path of seeking ESIC exemption in lieu of Medical Insurance policy.
In case you accept the above, you may consider one of the 2 options below:
Option 1: Continue with only ESIC for your employees.
Option 2: Continue with ESIC but in addition provide extra medical insurance. And employees can choose to use it if they find ESIC facilities not to their satisfaction.
Option 2 of course, is additional cost, but if the people are predominantly white collar and employee satisfaction and retention is a key criteria, such as in Product IT / R&D set-ups, then this additional cost should not be a major constraint in view of improved employee satisfaction or reduced attrition.
Those are my views for your consideration. Thanks.
