The Second Division of the Adjustment Board, upon the whole record ,and
Q all the evidence, finds that:










Form 1 Award No. 6636
Page 2 Docket No. 6464
2-SUU-CM-`74

Claim is f.-or payment of 49 hours and 25 minutes a t the time and onehalf rate, account not being called and used as extra derrick groundman with crew that was called on June 10, 1972 for the Haylow derailment.

We find no rule compelling Carrier to interrupt and send for an assigned extra groundman already out and at work on a road trip and return him to his home yard so that he may thereupon begin another assignment.

Employes allege that such was the established practice here but fail to meet Carrier's statement that the one instance cited in support thereof involved a regular derrick groundman as distinguished from extra man, Claimant's status. Rule 153, cited by Employes refers only to "regularly assigned crews". -We find unpersuasive Employes' contention that because he was taking the place of a regularly assigned derrick crew member who ,,?as on vacation, Claimant thereby became a "regular assigned crew member" for purposes of Rule 153.
