The president of the Ontario Secondary School Teachers' Federation says there is almost no chance to avoid a one-day strike set for Wednesday. Harvey Bischof says Education Minister Stephen Lecce is ratcheting up rhetoric around the tense talks instead of engaging in constructive bargaining. Lecce said giving high school teachers everything they want, and applying that to all education unions, would cost $7 billion over three years - a number Bischof and the NDP leader questioned.
