The contract with the union covers the 25 workers at the Saint John Airport and expired in December 2008.
Officials at the airport remain hopeful this labour action can be resolved and negotiations are continuing.
Colleen Kemp-Mitchell of the Saint John Airport says the negotiating team continues to work towards a settlement.
In the event of strike action, the airport will remain open with flights continuing as scheduled. No picket lines are up yet and all flight are running on time this morning.
