(a) If a teacher is required to work more days than provided for under the teacher's contract, then the teacher's pay under the contract shall be increased proportionately so that the teacher will receive pay for each additional day the teacher is required to work at no less than the daily rate paid to the teacher under the teacher's contract.
(b) Each school district in this state shall establish a normal base contract period for teachers.
(c) The normal base contract period for each school district shall be the number of days the majority of teachers employed by the school district in the 2000-2001 school year are required to work as specified on the 2000-2001 contracts as of March 1, 2001.
(d) If the normal base contract period in any school district is increased, the teacher's pay under the contract shall be increased proportionately so that the teacher will receive pay for each day added to the contract at no less than the daily rate paid to the teacher under the teacher's current existing contract.
(e) This section shall not apply to separate contracts for employment with a teacher to teach summer school or to perform services that do not require the teacher to hold a teaching license to perform those services.
(f) If the school district desires to employ a teacher part time to perform services for the school district in the teacher's field of licensure after expiration of the normal base contract, as part of the teacher's normal teaching contract, the school district may contract for such part-time work as long as the teacher is agreeable and is paid on a pro rata basis for that work.
(g) A school district which contracts with a teacher to teach summer school or to perform services that do not require the teacher to hold a teaching license to perform those services shall enter into a separate contract with the teacher for those services and shall not condition initial employment of the teacher or renewal of the teacher's regular teaching contract on entering into such a separate contract.
