Hello everyone. I am Umesh Sharma and worked as an Assistant Professor in a private engineering college on a regular basis for 4 years and 276 days (from 3-8-2012 to 5-5-2017). At the time of resignation, the HR staff told me that I was not entitled to gratuity as I had not completed 5 years. However, recently, I discovered that 4 years and more than 240 days are sufficient for entitlement to gratuity in India. I then submitted a gratuity application in December 2018 but have not received any response yet. If they don't respond to my application, where should I lodge a complaint regarding this matter?
