Toronto and District School Board (TDSB) will vote tonight on whether to authorize annual school proms using management staff like principals and other support employees to supervise the events. As it stands, the work-to-rule campaign by high school teachers appears to prevent any chance that they will be assisting in such dances. Students are said to be working hard to save the prom, with or without school support. The student council at Bloor Collegiate Institute has been looking at the possibility of planning a year-end party themselves. For the prom motion to pass at tonight’s meeting, it will need the backing of a simple majority — at least 12 out of 22 elected trustees.
