A substitute teacher is employed by the Division either to replace a regular teacher or to fulfill an assignment which is less than twenty (20) days in duration.
A substitute teacher who has been employed for at least twenty (20) days of extended substitute teaching shall, on the twenty-first (21st) day, be signed to a Limited Term Teacher contract, unless the return of the regular teacher or the conclusion of the substitute assignment will occur within five (5) working days.
A substitute teacher who is called to work and reports for the assignment finding that his or her services are not required shall be offered an alternative assignment of not less than one-half (1/2) day.
Unless otherwise determined at the time of the assignment, or except in unforeseen circumstances, the timetable for a substitute teacher in any extended assignment shall normally be the same as the timetable of the teacher who is being replaced.
