Workers at Aberdeen Airport will go on strike over their pay and pensions, a union has announced.

Unite said 88% of its members voted in support of industrial action on a turnout of 79%.

The union said airport bosses tendered a 3% pay rise offer following a consultation in January, but no agreement was reached on proposed changes to the staff pension scheme.

Aberdeen Airport is part of AGS Airports group, which also owns Glasgow and Southampton airports, with all three airports being subject to the pension proposal.

Shauna Wright, Unite regional industrial officer, said: "After this resounding result in favour of strike action at Aberdeen airport, AGS should be left in no doubt about the strength of feeling among Unite members.

"We recognise the movement on pay by AGS, but the sticking point remains the attack on our members' pension scheme. Talks through Acas are ongoing and Unite, once again, encourages the company to use this period constructively to find an agreeable resolution to this dispute.

"But, if the company don't, then they know that our members are prepared to fight to protect their hard-earned pensions through strike action or action short of strike during the busy holiday season."

An airport spokeswoman said talks would continue in the hopes of averting a strike.

She said: "Clearly we're disappointed at the result of the ballot, particularly as many staff will have cast their vote based on the initial pay offer of 1.8% which was subsequently increased to 3%. This was in line with the demands of the unions.

"During talks at Acas, the company also significantly increased its offer of compensation to pension scheme members, however, we remain open to dialogue and talks are set to continue.

"It's important to note there is no such thing as an Acas agreement. The trade unions are referring to an agreement made with the company in 2016 and which AGS has honoured in full."

The airport has "robust" contingency plans to ensure there will be no disruption to travellers, she added.
