The BC Public School Employers' Association has asked the B.C. Labour Relations Board to designate all services that are required to complete Grades 10 to 12 report cards as essential services.
Its application argues "serious and immediate damage" will be caused to secondary students' educational programs if final grades are not compiled.
The request comes in response to an announcement Wednesday by the B.C. Teachers' Federation that it will hold a strike vote on Monday and Tuesday seeking support from members for a full withdrawal of services.
Earlier this week, Education Minister Peter Fassbender pledged that all critical exams would be graded to avoid putting students in jeopardy.
The union is required to give three days notice before teachers walk of the job, and negotiators have been bargaining for the past two days and are scheduled to be at the table from Monday through Thursday next week.
