be applied to the occupants of positions that carried the rates in 1915, stated under the heading "Old Rates". In all cases where the "New Rates" are lower than the rates now in effect, for occupants of positions that in 1915 carried the rates named under the heading "Old Rates" the rates now in effect will remain undisturbed. The standard month upon which the schedule of increases is based, consists of the number of hours (whether 8, 9, 10, 11 or 12) constituting the standard day, multiplied by 26 days for six day workers, and 30 days for 7 day workers. Overtime, where now called for by rules, schedules or agreements, begins at the end of the standard present day. These rules will apply to foremen, chief clerks and others employed in a supervisory capacity as well as to their subordinates. |
