The Windsor-Essex Catholic District School Board says it's going over all of its options after a judge rejected its application for an injunction Friday.
The injunction would force striking support workers to allow teachers through the picket lines.
Teachers have been waiting up to hours at some high schools, leaving students waiting for class to start in school cafeterias and gymnasiums.
School board spokesman Stephen Fields says the judge also urged the board to refile the application this week.
Meanwhile, the school board has called a news conference for late Monday morning.
The strike by 370 support workers is into its third week.
