If you're planning a trip to Newfoundland, now might not be the best time. Airport workers in St. John's have voted unanimously in favour of striking.

The 90 members of the Public Service Alliance of Canada's Union of Canadian Transportation Employees voted 100% in favour of a strike mandate on Thursday night.

"The bargaining committee has the full support of the membership," UCTE spokesman Wayne Fagan said in a statement. "Airport workers are strike-ready."

The employees -- who clear runways, build and maintain equipment and take care of emergency services -- said the St. John's International Airport Authority hasn't given them a pay increase in four years.

Both parties will work with a mediator this week, but if it doesn't work out, the workers could be on the picket line as early as next week.
