Workers at Aberdeen Airport will strike for two days next month amid a dispute over pay.
Unite has announced its members will take industrial action at the Aberdeen terminal on June 7 and 10 between 4am and 4pm.
It follows a breakdown in talks about pensions and pay with owners AGS Airports.
Shauna Wright, Unite regional industrial officer, said: “Unite members at Aberdeen Airport will join those at Glasgow Airport taking industrial action to fight against this coordinated attack by AGS on our members’ pension scheme.
“We have repeatedly warned AGS that if they do not keep to the agreements they made with us then industrial action would be inevitable.
“Let’s not forget that this attack comes despite Aberdeen Airport having enjoyed a near doubling of their profits.
“Industrial action is now set for June and further dates will be forthcoming, causing widespread disruption during the summer period due to the broken promises of AGS.”

Those taking part in the action include firefighters, taxi marshals and airfield operations workers.
Pat McIlvogue, Unite regional industrial officer, said: “The company are insistent upon abolishing a scheme they agreed to only three years ago while the boardroom enjoys pre-tax profits of £91 million.
“Our members deserve better. So this is not about saving money, it is about attacking our members’ terms and conditions.
“Industrial action is now set for the summer period and the blame for that lies fully with Glasgow Airport.”
