Hours after some flight attendants walked off the job, the Canadian government has stepped in to put an end to a strike that has created travel chaos at home and around the world.

On Saturday, the union representing flight attendants blasted the government’s decision, saying it violates their Charter rights. Sean O’Shea reports.
