I started working for a company on 1st October 2012. My training period was for 2 years, and it ended on 1st October 2014. After that, my company put me on probation for 6 months, which ended on 1st March 2015. However, until now, my company has not provided me with my confirmation letter, and they have not given me any extension letter either. They have issued confirmation letters to all my fellow workers. What should I do? Should I take any legal action? If yes, then how? Kindly, please help me. I don't know what to do.
