Bilingual Pay Differential

Just recently one of our members brought to my attention that in CA and AZ clerks are paid some sort of differential for their bilingual skills. As a former interpreter I have often wondered why such an important skill ceased to have value (to OCA) once I became a clerk. In the courtroom we always have an interpreter available. However, at many information desks and front counters it is a bilingual clerk that is called upon to assist these court users. What do you think? How many of you are using this skill on a regular basis. Should this be the basis for some sort of pay differential? Is it fair to those members that do not speak a second language? JM
