Baggage handlers and other ground staff at Stansted Airport are to go ahead with a four-day strike over the Jubilee weekend after talks failed to resolve a row over new rosters.
Members of the GMB and Unite employed by contractor Swissport have already taken industrial action, although the company said it failed to have any impact on passengers.
The unions claimed new rosters threatened pay cuts for their members.
A union source said two sets of talks this week had not made enough progress for the strike to be called off.
Workers will strike for four days from Saturday morning.
