I have been working in iit guwahati as a project assistant since November 2011. My contract was till December 2015. But it was supposed to be renewed in january as our tenure is extended in every 3 months. All my project mates got extension letter through mail on 28/1/2016 except me. When i asked our pi (project in charge) about the same he just said that i will get extension but did mot say when. Then i gave him a written application asking for any updates regarding my extension. He didnot reply. Then i asked R&D section (R&D section looks after everything related to projects in iitg). They also didnot reply to my mail. It was clearly written in the appointment letter that they must inform me one month before my termination but they did not. Now what should i do.
