Teachers are set to walk off the job for a second time in a month after contract talks broke down Thursday.

The Saskatchewan Teachers' Federation has confirmed teachers will withdraw all services next Wednesday and Thursday.

The strike dates coincide with both the Saskatoon and Regina city track and field meets, which means those event will be cancelled.

Teachers are now asking for a 16.3 per cent wage increase over three years. Previously, they had asked for 12 per cent over one year.

The provincial bargaining committee has offered 5.5 per cent over three years.

A spokesperson for teachers says the province and the Saskatchewan School Boards Association are devaluing teachers.
