Cal. Educ. Code § 88087

The commission shall recommend to the governing board salary schedules for the classified service. The governing board may approve, amend, or reject these recommendations. No amendment shall be adopted until the commission is first given a reasonable opportunity to make a written statement of the effect the amendments will have upon the principle of like pay for like service. No changes shall operate to disturb the relationship which compensation schedules bear to one another, as the relationship has been established in the classification made by the commission.
