Rail workers pushed back hard Friday against the federal government91裸聊视频檚 move to get them back on the job, with a new strike notice and a regulatory challenge making it unclear when freight traffic will fully resume.

At Canadian National Railway Co., trains began to move again Friday morning as workers started to trickle back to work 91裸聊视频� even as the Teamsters union issued a 72-hour strike notice against CN shortly before 10 a.m. EDT.

And at Canadian Pacific Kansas City Ltd., the union has challenged a directive for binding arbitration issued by Labour Minister Steven MacKinnon to the country91裸聊视频檚 labour board.

A work stoppage at both national railways prompted MacKinnon to ask the Canada Industrial Relations Board on Thursday to use the mechanism, aimed at resolving an impasse that has halted freight shipments and snarled commuter lines across the country.

The labour board summoned the parties to a meeting Thursday night, followed by a hearing Friday morning.

The tribunal said in an email it is addressing the issue 91裸聊视频渨ith utmost urgency.91裸聊视频� A decision is expected later in the day.

Pickets continue at the head office of CPKC in Calgary and those on the line received a visit from Francois Laporte, the national president of Teamsters Canada Friday morning.

Laporte and Sean O91裸聊视频橞rien, the general president of the International Brotherhood of Teamsters arrived in a black semi truck, its horns blaring, with Teamsters written on the side.

O91裸聊视频橞rien called the lockouts by both rail companies 91裸聊视频渁 disgrace.91裸聊视频�

91裸聊视频淭his is not over. I91裸聊视频檓 telling you this is not over. The struggle continues,91裸聊视频� Laporte said to about 70 people who were on hand.

Before making the binding arbitration directive, the labour minister had faced pressure to intervene from business groups, which warned of the economic consequences of the work stoppage and urged Ottawa to break the deadlock and kick-start freight service.

At a Thursday news conference, MacKinnon said the government is 91裸聊视频渃ommitted totally to collective bargaining,91裸聊视频� but said the impacts of the shutdown are being felt by all Canadians.

The government gave the negotiations 91裸聊视频渆very possible opportunity to succeed,91裸聊视频� he said.

Each side had accused the other of failing to negotiate seriously, with wages and scheduling as key sticking points. The union had said it rejected binding arbitration, framing Ottawa91裸聊视频檚 decision as a move to 91裸聊视频渟idestep91裸聊视频� it.

91裸聊视频淒espite claiming to value and honour the collective bargaining process, the federal government quickly used its authority to suspend it, mere hours after an employer-imposed work stoppage,91裸聊视频� said Paul Boucher, president of the Teamsters Canada Rail Conference, in a release Thursday evening.

The union has said both companies are pushing to weaken protections around rest periods and scheduling. It says CN also seeks a scheme that would see some employees move to far-flung locations for several months at a time to fill labour gaps.

CN pushed back on Friday, saying the Teamsters are 91裸聊视频渉olding Canada hostage to their demands.91裸聊视频�

91裸聊视频淐N is focused on recovery in order to resume powering the economy. The Teamsters are focused on returning to the pickets and shutting everything down again,91裸聊视频� said spokesman Jonathan Abecassis in a phone interview.

In Calgary, Laporte said he understood that the Teamsters at CN gave 72 hours strike notice this morning and as far as he91裸聊视频檚 concerned the dispute will continue.

91裸聊视频淥ur people are still on strike. We91裸聊视频檙e still on the streets so our operation will not resume. It is not going to be business as usual for both companies.91裸聊视频�

O91裸聊视频橞rien said the International Teamsters fully support their Canadian colleagues.

91裸聊视频淐orporate greed is running rampant,91裸聊视频� he told reporters at a picket outside CPKC headquarters in Calgary on Friday morning. 91裸聊视频淩eward these workers with what they have earned. But also don91裸聊视频檛 try to diminish safety.91裸聊视频�

91裸聊视频淲hat91裸聊视频檚 important here is not to lose sight of the fact of who caused this problem right now. They chose to lock these workers out,91裸聊视频� O91裸聊视频橞rien said.

91裸聊视频淲e got your backs 100 per cent.91裸聊视频�
