Sap past three years. The increase in program requirements for research and development and production activities necessitated a rapid acceleration of employment, culminating in a total of 5,447 employees on a payroll as of June 30, 1953. No appreciable increase over this figure is anticipated during the coming year. In order to obtain the net increase of 3,401 employees during the three-year period, it was necessary to hire 5,570 persons at an average rate of 154 per month. The average monthly separations during this period was 1.5 per cent per month, compared with a national average of 4 per cent per month.
