I resigned from my job in 2004 at a Delhi-based company where I worked in the Tirupur branch. They kept my name in one concern for 3 years and then transferred it to their sister concern for another 2.5 years. In both companies, I was in the PF role. Now, they are denying my eligibility for gratuity. Can anyone help me with how I can go about claiming it? Am I eligible for it or not?
