Neha,
The Act provides for the payment of gratuity to workers employed in every factory, shop, and establishment or educational institution employing 10 or more persons on any day of the preceding 12 months. A shop or establishment to which the Act has become applicable shall continue to be governed by the Act even if the number of persons employed falls below 10 at any subsequent stage.
All the employees, irrespective of status or salary, are entitled to the payment of gratuity on completion of 5 years of service. In case of death or disablement, there is no minimum eligibility period. The amount of gratuity payable shall be at the rate of 17 days' wages based on the rate of wages last drawn, for every completed year of service. The maximum amount of gratuity payable is Rs. 3,50,000/-.
Formula: Last Wages * 15 * No. of services / 26
