The ray of hope in the postal dispute Friday morning was snuffed out by last night. The Canadian Union of Postal Workers had asked for a 30-day truce to keep talks going and keep the mail moving. Canada Post said sure – so long as both sides agree to binding arbitration if they can’t get a deal done in that time. The union would not agree to that. A lockout remains likely as of 12:01 Monday morning, bringing mail service across the country to a halt.
