In every case in which specific statutory increases in the amount of any salary of the holder of any office, position or employment are provided, such specific statutory increases hereby are abolished and abrogated; provided, the Civil Service Commission shall establish automatic increases in such salary, based upon length of service, within the salary ranges established from time to time therefor, and such salary shall thereafter automatically be increased accordingly, unless the head of the department and the Civil Service Commission shall agree that the service record of the holder of such office, position or employment does not warrant any such increase in salary.
