1. DECISION ' The appellant was appointed as Auto Electrician in the respondent's Corporation with effect from 1-2-1992. On 15-6-1992 his services were orally terminated without assigning any reason. It is the case of the appellant that he had completed three months of service and he had therefore become permanent. It has however been admitted by the appellant in his cross-examination that he had not sent any grievance notice to the Karachi Transport Corporation before filing his grievance petition under section 25-A of the I.R.O. Under section 25-A it is a mandatory provision of law that the worker is required to bring his grievance to the notice of the employer in writing within three months of the day on which the cause of such grievance arises. Without service of this notice the grievance application before the Labour Court is not maintainable. His application was accordingly dismissed by the Labour Court as being not maintainable and I can see no reason to interfere. This appeal therefore stands dismissed.
