Labour Minister Patty Hajdu says while Ottawa still believes the best solution to a labour dispute is a negotiated deal, her Liberal government has given the House of Commons 48 hours notice that it is prepared to order an end to a month of rotating strikes by Canada Post employees. Hajdu says the two sides have already had a long time to negotiate a contract agreement, but she expects them to work hard over the next couple of days with a special mediator to work things out. The union alleges a back-to-work order is what Canada Post has been waiting for. CUP-W is also taking issue with the scale of the backlog that the post office claims the job action has created and insists it could be cleared in a matter of days.
