I am working in a private company since June 2004. from June 2002 to March 2012 I received salary in cash, after march 2012 to march 2016 I received salary by cheque and after April 2016 I received salary in account also PF deduction started from 2016. Now I have resigned from the company after 16 years and five months of my job so my question is - Am I eligible for gratuity or not?
