Thank you very much for your insight on the subject. Every contract signed was for a period of one year (i.e., from 12/07/2010 to 11/07/2011, 12/07/2011 to 11/07/2012, 12/07/2012 to 11/07/2013, 12/07/2013 to 11/07/2014, 12/07/2014 to 11/07/2015, and the final agreement was from 12/07/2015 to 11/07/2016). Every year, a new agreement was signed with a change in remuneration/honorarium only, keeping all the terms and conditions the same. There was no mention of payment of gratuity in any of the agreements. The agreement can be terminated by giving one month's notice by either party. It also states that "The said contract stands terminated on its expiry unless renewed."
After the final agreement, HR informed me that hereafter no new agreement will be made, and my services are not required. I was following the attendance rules and regulations of the company, receiving 28 days of leave, being a member of the employees' group insurance scheme, along with the agreed monthly remuneration. I did not sign any invoice for the services rendered. On my full and final settlement receipt for the last 11 days period (from 01/07/2016 to 11/07/2016), the Date of Joining is stated as 12/07/2010, and the Date of Leaving as 11/07/2016. If you permit me, I will call you, and if I get your email ID over the phone, I can email you my contract copy for your further advice.
Thank you again, and my sincere apologies for disturbing you.
Regards,
Deepak Nayak
