Thanks everybody for your advice and sympathies.
Went to the local C.A.B and the co-ordinator out there was referring to ACAS website to establish if my redundancy was unfair. In other words she was not qualified but just working voluntarily. Anyways, called ACAS and they asked me to file an appeal with the employer first and wait for at least 2 weeks before taking the case to Tribunal if the employer's response is not satisfactory.
