Upon commencement of the sixth (6th) day of substitute teaching in the same assignment, a substitute teacher shall be paid for each day taught at the per diem rate (to be calculated as 1/x of the salary to which a teacher of the same qualifications and experience would be entitled under the basic salary schedule of the current collective agreement, where x equals the number of days in the current school year).
This rate of pay shall be retroactive to the first day of the teaching assignment and shall continue in effect until the end of that specific teaching assignment. In-service days, administrative days and school closure days shall not constitute a break in the consecutive days for that specific teaching assignment.
