Dear Suriya,
The remedy depends on the capacity of your job before your termination. If you are a workman u/s 2(s) of the I D Act,1947, you can file a dispute u/s 2-A(1) of the Act before the Labor Officer for your area against the Company and the Officer's intervention will help to arrive at an amicable settlement of all your dues.
