PARTIES TO DISPUTE:


STATEMENT OF CLAIM: Claim of the System Committee of the Brotherhood that:

(1) The Carrier violated the Agreement when it assigned Mechanical Department employes instead of Bridge and Building Department employes to assemble and install lockers in the Enginehouse Locker Room'at Pueblo, Colorado on November 16, 17 and 21, 1974 (System File D-6-75/MW-4-75).

(2) The members of B&B Gang No. 6003 each be allowed pay at their respective rates for an equal proportionate share of the total number of hours expended by Mechanical Department employes in performing the work referred to in Part (1) hereof.

OPINION OF BOARD: This dispute concerns the assembling and/or installing of
lockers in the Enginehouse Locker Room at Pueblo, Colorado,
which is alleged to be the work of Bridge and Building forces. The work in
question was performed by machinists who have indicated that the work is not
within the scope of their agreement.

Without considering the procedural question raised by Carrier, the issue herein is whether or not the work in question should have been assigned to Claimants. The only reference to the Agreement by Petitioner on the property is the claim that the work is covered by the Scope Rule. The Scope Rule of the applicable Agreement has been before this Board on numerous occasions and has uniformly been termed a general rule (e.g. Awards 15221, 11+877, 14638, and 11831). The Board has held that in order to establish rights to particular work under this Agreement and general rule, the Organization must establish by probative evidence that employer covered by the Agreement have in the past performed the disputed work to the exclusion of all others. In this dispute the Organization has offered no evidence whatever to support its contentions. Accordingly, the Claim mast be dismissed.





That the Carrier and the Employes involved in this dispute are respectively Carrier and Employes within the meaning of the Raiiway Labor Act as approved June 21, 1931+;

That this Division of the Adjustment Board has jurisdiction over the dispute involved herein; and
