Teamsters union files lawsuits against Canadian government-issued back-to-work orders over railway strike.

The Teamsters union representing Canada's two largest freight railroads has filed lawsuits challenging government-issued back-to-work orders, which forced employees back to work and ended the railway strike.

The government has ordered the union to remain on the job during the arbitration process.
