 Claimants are employed as carman welders by Carrier at its Raceland Car Shop in Russell, Kentucky. From August 31 through September 4, 1984, Carrier assigned sheet metal workers to build, weld, and install a steel cabinet for use in an electrical power car for camp car forces. The Organization thereafter filed a claim on Claimants' behalf, challenging Carrier's use of sheet metal workers to perform this work.

 This Board has reviewed the record in this case, and we find that Supplement No. 6 requires that jurisdictional disputes must first be handled between the General Chairmen of the crafts involved before any other processing of the claim occurs. In this case, the record does not indicate that there was any handling of the matter between the General Chairmen of the two Organizations. Therefore, since the provisions of Supplement No. 6 were not complied with by the Organization, this claim will be dismissed in accordance with our usual procedure.
