(e) Salaries for employment beyond the minimum employment term shall be at the same daily rate as the salaries for the minimum employment terms.

(g) No county may reduce local funds allocated for salary increments for principals and assistant principals in effect on January 1, 2008, and used in supplementing the state minimum salaries as provided in this article, unless forced to do so by defeat of a special levy, or a loss in assessed values or events over which it has no control and for which the county board has received approval from the state board prior to making the reduction.
(h) Nothing in this section prevents a county board from providing, in a uniform manner, salary increments greater than those required by this section.
