Recognizing that an adequate lunch period free from duty is essential to the health, morale and efficiency of teachers employed full time in any regular day school, the Legislature declares that it is the policy of the state to encourage school districts to provide for an adequate duty-free lunch period for teachers.

In order to provide for such duty-free lunch periods, the governing board of any school district may utilize recreation personnel or other suitable persons to supervise the pupils of the district during the school lunch period.

The provisions of this section shall prevail over any provision of Section 44813 which conflicts herewith.
