 PARTIES TO DISPUTE: (
 (The Denver Union Terminal Railway Company

 STATEMENT OF CLAIM: Claim of the General Committee of the Brotherhood of Rail
 road Signalmen on the Denver Union Terminal Railway Company
 that:

 (a) The Denver Union Terminal Railway Company violated the current Agreement with the Brotherhood of Railroad Signalmen effective September 1, 1949, including revisions, when it abolished the position of Signalman No. 4 in violation of Rules 13, 20, and 63, requiring incumbent to suspend work on regular work day, and work to him at the straight time rate in an effort to evade application of the rules of this Agreement.

 (b) Mr. G. J. Miller be allowed 16 hours at $3.9055 and 16 hours at 1/2 x $3.9055, totaling $93.73, in addition to any other compensation earned by him during the month of December, 1969. (General Chairman's File: GTM-12-29-69. Carrier's File: 018.1)

 OPINION OF BOARD: This case involves a change in Claimant's assignment for a
 seventeen day period just prior to Christmas in 1969. The
 change in position, accomplished by a series of bulletins, resulted in Claimant
 doing the same class of work, in the same place and at the same pay; the only
 change was in the work days, shifts and hours.

 Petitioner alleges that the change was made for the sole purpose of avoiding payment of overtime to Claimant for one shift each of two weeks. Carrier contends that the the purpose of providing adequate service during the pre-Christmas mail rush and were identical with changes in assignments made at the same time over the previous seven years.

 This case involves the same parties, employees and circumstances (merely a different Claimant) as those involved in Award No. 19638 which this Board, with the same Referee participating, recently decided. In this case as in the previous matter, we hold that the perogatives of management, unless limited by the Agreement or the law, must remain vested in the Carrier. This principle has long been affirmed by the Board. (See Awards 11793, 11776, 12358, 13490, 16851 and many others). As we said before, the right to manage includes the right to change work assignments or schedules to effect economies (including saving on over-time) as long as these changes are not prohibited by the Agreement.
