Aberdeen airport workers are set to strike, after rejecting the latest pay offer.

Members of Unite took a consultative ballot on the improved pay offer of 2.8%, which is 0.2% short of what the union is demanding.

On Tuesday afternoon, Unite confirmed their members have rejected the offer, saying it is a "pitiful effort" by the airport to end the dispute.

Around 170 workers at the airport are now set to strike for a series of 24 hour periods on July 20, August 2 and August 16.

The workers taking action include security and airfield operations, airside services, firefighters, operations officers and passenger service agents.

Unite regional coordinating officer, Tommy Campbell, said: "The latest pitiful effort by Aberdeen International Airport to end this dispute has been overwhelmingly rejected by Unite members.

"The management seem more intent on causing widespread disruption to their operations - and the public - on the basis of not being prepared to give our members the same pay award as the workforce at Glasgow International Airport, which is owned by the same parent company.

"The workers and the public at large will be baffled as to why airport management are refusing to pay an extra 0.2% to end this dispute today and in doing so will cause more financial harm and damage to their reputation.

"Unite remain open to further discussions with a view to resolving the dispute if the company start to behave responsibly, if they do not, then our members will have no option but to proceed with industrial action."

A spokesperson for Aberdeen Airport said: "Talks with staff representatives concluded in a positive place on Monday following a much improved offer and we are extremely disappointed to have had our latest pay proposal rejected.

"We are in ongoing discussion with Unite and remain optimistic that we will resolve matters without any impact on operations at the airport."
