 STATEKM OF CLAIM: "Claim of the General Committee of the brotherhood of
 of Railroad Signalmen on the Southern Railway Company et al:

(a) Carrier violated the Signalman's Agreement, particularly Scope Rule 1 among others, when C&S Supervisor H. H. Stanley worked the first shift at Sheffield Retarder Yard on July k, 1980 assisting Signal Maintainer J. W. Hamilton in the painting, rearranging and moving signal material in and around signal shop at Sheffield Retarder lard, etc.' (Big. file 3460)

 (b) Carrier should now be required to compensate Signalman J. R. Scott as amount equal to eight (8) hours at the time and one half rate of pay for this lass of work opportunity on July 4, 1980 and because the Agreement was violated."

 OPINION OF BOARD: The Mmploye asserts that individuals covered by the Agreement
 had been "cleaning up" the atop area for an inspection but
 far some reason a Supervisor started performing some of the work in question.

 In its initial response the Carrier concedes that the Supervisor did clean the paint sprayer which signal maintainers had used on the previous day and which they had not cleaned at the conclusion of their task. The Carrier also concedes that the Supervisor may have moved certain equipment so as to try a new grease cleaner on a spot on the concrete floor with a new type of solvent.

 The organization has relied upon Awards 23959 and 24296. The Board is of the opinion that the Organization has presented the basis for a sustaining Award inasmuch as certain work was performed which we feel, under all circumstances of record, ahoa1
We confess that there is some question as to the amount of time involved in the performance of t mattes was under review on the property far as to make a determination in that regard, and accordingly we will sustain the claim as submitted.
