RULE 31-

BRAKEMEN FILLING TEMPORARY VACANCIES AS CONDUCTOR -- HOW PAID

Brakemen or yardmen filling temporary vacancies as conductors for ten days or less will be paid in accordance with rates and rules governing the service performed, but not less than they would have earned had they continued on their regular turn or assignment, except that when in accordance with schedule rules a senior unassigned conductor displaces a junior unassigned conductor who is filling such a temporary vacancy, the conductor making the displacement will be paid in accordance with rates and rules governing the service performed.

NOTE: In the application of this rule loss or difference In earnings during the ten‑day period shall be calculated from the time compensation begins to accrue in conductor service and will end when the brakeman resumes service on his regular assignment.

A brakeman used in service as a conductor in order to qualify for payment under this rule, must keep himself available for further service as a conductor out of the home terminal during the ten‑day period and should he miss, lay off or refuse a call for further conductor service, the earnings of the employee used in his stead shall be weighed against the earnings of the employee's assignment as a brakeman in determining the loss or difference of earnings.
