The sidewalks outside of some public high schools in Sudbury may look a little different Thursday morning.

The teacher's union has informed the Rainbow District School Board that it may hold information pickets at some schools on Thursday.

Rainbow board high school teachers took their weeks-old job action to new levels this week. The teachers have stopped doing anything but teaching, including extra-curricular activities, supervising students outside of the classroom and communicating with parents.

Classes will not be affected.

Parents looking for updates in this ongoing labour action should consult the board's web site:
