@ LEKSHAMI AMPATTU,
The current ESIC exemption limit is ₹15,000 Gross. As per your state's rule, if any organization has 10 or more employees and if any of the employees' salary is less than ₹15,000 gross Salary, ESIC is applicable. According to the ESIC Act, the employee or employer cannot deny the benefits of the social benefit scheme.
You may search for more information on this rule on your local website: [Employees State Insurance Corporation (ESIC), Kerala - http://esickerala.gov.in](http://www.esickerala.gov.in)
Hope this information helps you.
