Stansted baggage handlers have voted to strike over the Easter weekend in a dispute over pay.
The GMB union members voted for action as they believe shift changes could leave them £1,000 worse off per year.
The union have asked airport contractor Swissport to reconsider but say the strike, on April 6, 7 and 9, will go ahead if there is no progress.
Gary Pearce, GMB Organiser said, “GMB members have voted overwhelmingly for strike action and for action short of a strike.
"Up to now the company has been intent on imposing these changes without agreement and this is completely unacceptable as this vote shows.
"GMB has offered several alternative shift patterns and working arrangements but the company refuses to listen so far. I have notified Swissport of the ballot result and I have asked them for more talks to try to avert action over these pay cuts."
He warned travellers would face disruption.
