The Board, after hearing upon the whole record and all evidence, finds that the parties herein are Carrier and Employee within the meaning of the Railway Labor Act, as amended, that this Board is duly constituted by Agreement dated January 5, 1959, that it has jurisdiction of the parties and the subject matter, and that the parties were given due notice of the hearing held.
The Board has been presented with evidence that Claimant, on May 18, 1987, resigned his employment with Carrier and by so doing waived any and all claims arising under the labor contract which were either pending on the property or progressed to a tribunal, such as this Board, for final adjudication. This Board lacks substantive jurisdiction to decide the matter.
