One of our employees who worked with us from May '08 to May '12 and then resigned. After 8 months, he rejoined from Dec '12 and resigned again in Dec '17. Now, he is asking for gratuity from May '08. Is he eligible for gratuity as per his requirement, or is he eligible for the period from Dec '12 to Dec '17 only as per the act? Does anyone have any precedents for such cases of breaks in service and requesting full gratuity?
