 PARTIES TO DISPUTE:


STATEMENT OF CLAIM:

 1. That the Baltimore and Ohio Railroad Company violated Rule 125 of the Controlling Agreement, when on June 25, 1989, Supervisor W. Rice removed at two-way radio from locomotive unit 6034 and applied a two-way radio to locomotive unit 6109; and accordingly.

 2. That the Baltimore and Ohio Railroad Company compensate Electrician Frank Grim an amount equal to two hours and forty (2:40) minutes at the then effective straight time rate of pay.

 On June 25, 1989 the Carrier assigned a Supervisor to remove a two-way radio from Locomotive 6034 and to apply the radio to Locomotive 6109 at its Locomotive repair facilities located at Cumberland, Maryland.

 The Organization's claim alleges that the assignment violated Rule 125 of the Agreement because the work is reserved exclusively for Electricians. The Organization seeks "an amount equal to two hours and forty minutes at the then effective straight time of pay."

 In companion cases involving the same parties and virtually the same issues, the Board denied the claims, partially on the grounds that the contested work, which also included an RDU unit as well as a Track Star Radio, was de minimus in nature. See Second Division Awards 12238 and 12239. In the present case the Board finds nothing in the facts and circumstances and the arguments of the parties to justify a different conclusion.

 The work performed by a Supervisor on June 25, 1989, of removing a two-way radio from one locomotive to another, was, among other things, of a de minimus nature. Accordingly, the claim is denied.

        Claim denied.
