Madison Teachers, Inc. Newsletter, via a kind Jeannie Kamholtz email (PDF):

Some principals appear to be confused about scheduling of parent-teacher conferences. The following is the AGREEMENT between MTI and the District as regards scheduling of parent-teacher conferences, and whether or not teachers are obligated to report to school on Friday, November 15.
“Section V-M of the MTI / MMSD Collective Bargaining Agreement will be implemented by evening conferences being scheduled on two evenings after the regular school day (November 12 and 14 for 2013). No school will be scheduled for Friday of the week of evening conferences. Teachers can hold conferences for parents wishing conferences, but who could not make one of the two evenings, or teachers can agree to conference with the parent(s) at another mutually agreeable time/date. Teachers who complete all conferences during the two evenings or agree to hold conferences at times other than on Friday for those parents who could not make the evening conferences, need not report to school on Friday. Teachers will not be required to be present during the parent-teacher conference day once their parent teacher conferences are complete, or are scheduled to be completed.”
