Federal workers to strike Wednesday if union, government don't reach deal by Tuesday

The country's largest federal public service union says if a deal isn't reached with the federal government by 9 p.m. EDT on Tuesday, it will launch a strike this Wednesday.

The Public Service Alliance of Canada says some 155,000 employees are prepared to walk off the job, including 35,000 workers from the Canada Revenue Agency.

Mediated contract negotiations between the union and the Treasury Board continued over the weekend in what the union described as the government's final chance to reach a deal.
