I am working with a private bank since February 2007. Now, I got another offer from a different bank, and they agreed to the notice period of 3 months. So, I will be joining there in January 2012, i.e., I will complete 4 years and 11 months. My question is, am I eligible for gratuity, and if my previous company is not ready to pay me the gratuity, what can I do for the same? Please help me in this regard.
