When reallocation is necessary because the director creates, abolishes, or revises a class, an employee's base salary is determined as follows:

(1) An employee occupying a position reallocated to a class with the same or lower salary range must be paid an amount equal to his/her previous base salary.

(2) An employee occupying a position reallocated to a class with a higher salary range must have his/her base salary adjusted to the same step in the new range as held in the previous range unless otherwise determined by the director.
