A Monday lockout deadline looms by Canada Post as the Canadian Union of Postal Workers rejected a counter-offer by the Crown corporation to go to binding arbitration at the end of a 30-day cooling off period.
The union had proposed the month long truce that would have seen the two sides enter into intensive negotiations.
However, Canada Post said they would only agree to the offer if the union would agree to enter into binding arbitration if no deal was reached.
CUP-W says agreeing to binding arbitration would take away their right to a negotiated settlement.
Canada Post will be in a legal position to lock out its 50,000 employees at 12:01 a.m. Monday.
Negotiations are stalled over pay equity as well as employee pension plans.
