Air Canada union serves strike notice

The union representing customer service and sales staff at Air Canada has given the airline a 72-hour strike notice.

That notice allows members of the Canadian Auto Workers to walk off the job at 12:01 a.m. Tuesday if the two sides cannot reach a deal.

Negotiations are ongoing and will continue right up until the deadline, said the union, which represents 3,800 Air Canada workers.

In a statement, Air Canada said if a settlement cannot be reached and the CAW does go on strike, "the airline has a contingency plan to continue operating a full schedule and minimize impact on customers."

A proposal to change pension plans for new employees is a key issue in the negotiations.

On Thursday, about 400 workers and labour rights activists rallied at Toronto's Pearson airport.
