To minimize the impact of Thursday's one-day teachers' strike, schools in the Upper Canada District School Board will remain open.

Parents are asked to try to find other arrangements, but if they can't, children are welcome to attend.

"Given the time of year and given many families’ situation, finding alternative childcare is difficult," said David Coombs, board superintendent. "In fact, some parents may have to miss a shift at work and it just is not feasible for them to do that. So we felt an obligation."

Students will be supervised in large central areas, such as gymnasiums.

Regular school programming will not be offered.

"Parents are reminded to let the board know if their children will be at school on Thursday during the strike so principals can plan for supervision," said a media release issued Monday. "They are asked to 'preregister' their children by submitting the special form that went home last week to let principals know if their children will be attending that day. Parents can also phone their school, email their principal, or contact their child’s school through school Facebook sites to advise the principal."
