Accounts & Statutory Like Esi, Pf, Kvat,
According to me you should not resign, but instead should take a transfer,
Please check what will be your DOJ with new co. it should be the one when you joined X co.
then only Gratuity facility will be liable to you if you complete your 5 yrs in X co.
Otherwise, after resignation you will be treated as NEW EMPLOYEE.
