The Saskatchewan Teachers’ Federation is locked in a contract dispute with the provincial government.

Starting Thursday, teachers are to start withholding services, including supervision of all extracurricular activities.

The issues at the heart of the dispute are classroom size and classroom composition. The union wants those matters included in the collective bargaining agreement, while the province believes they should be dealt with at a division level.

980 CJME and 650 CKOM will have the latest on the labour disruption right here.
