The Fredericton International Airport could be hit by a strike Monday morning if an agreement isn't reached with the union representing maintenance and support staff.

John Hamilton, of the Fredericton Airport Authority, said talks with a federal mediator have been underway all weekend.

But unless there's a breakthrough, he said, the 25 members of Local 60601 of the Canadian Transportation Employees Union, responsible for the general upkeep of the airport building, could walk off the job at 5 a.m. Monday.

If that happens, he said, six managerial employees will take over maintenance duties.

Since the dispute does not involve any airline employees, Hamilton said, air travel should not be disrupted.

"So any baggage handling, check-in, de-icing of aircraft and everything else is not affected at all," Hamilton said.

Fifteen of the 25 unionized workers are deemed essential under their contract, he said, so they would have to work in the case of a major problem such as clearing runways in the event of a snowstorm.

"All essential services, like making sure runways and everything are open, will go ahead as normal," Hamilton said.

Passengers are advised to arrive at the airport a little earlier than usual in case there are delays caused by picket lines should the workers go on strike.
