As per the Indian Gratuity rules, a person needs to complete 5 years with a company. Suppose a person joins a proprietary company which does not provide for gratuity. After 4 years, the company becomes a Pvt Ltd and starts providing gratuity. Now, if the employee leaves after 3 years, the total service is 7 years, but the period under the Pvt Ltd is only 3 years. Will the employee be eligible for gratuity?
