Pub. L. 83-74, tit. I, sec. 102

Sec. 102. (a) The annual basic salary of each officer and member of the Metropolitan Police force in a grade above that of private, class 3, except the Chief of Police, shall be increased by $120 at the beginning of the next pay period following each five-year period of continuous service completed in such grade, including service in such grade rendered prior to the effective date of this Act: Provided, That in computing service rendered prior to such date by any individual in the grade of private, only service in such grade in excess of three years shall be creditable in determining such increase or increases for any individual assigned to the grade of private, class 4, in the foregoing salary table. The annual basic salary of the Chief of Police shall be increased by $200 at the beginning of the next pay period following each eighteen-month period of continuous service completed in such grade including service in such grade rendered prior to the effective date of this Act. For the purpose of this subsection, service shall not be deemed to have been discontinued by reason of any assignment (with an accompanying increase in basic salary) pursuant to subsection (b) or subsection (e) of section 101 of this Act. An increase in basic salary under this subsection shall be known as a "longevity increase”. (b) Any officer or member who is promoted to a position in a higher grade in the foregoing salary table who is receiving one or more longevity increases under subsection (a) of this section, and whose basic salary, as increased by such longevity increases, exceeds the scheduled rate for such higher grade, shall, upon promotion, be entitled to the basic salary of such higher grade plus so many equivalent longevity increases as may be necessary to make his salary in such higher grade at least equal the salary he received before promotion, including longevity increases. 67 Stat. 74 (c) Whenever any officer or member is demoted from any grade to a lower grade and such officer or member prior to such demotion was receiving one or more longevity increases, the Commissioners, in their discretion, may in demoting such officer or member fix his annual basic salary so as to exclude all such earned longevity increases or to include one or more of such earned longevity increases. (d) The Chief of Police shall receive no more than four longevity increases and no other officer or member shall receive more than five longevity increases with respect to service rendered in any one grade. (e) No officer or member shall be entitled to a longevity increase for a five-year period of service unless he has maintained a rating of satisfactory or better for such period.
