Holidaymakers using Glasgow Airport could face disruption this summer as security staff are balloted for strike action in a pay dispute.
Around 170 ICTS central search workers have rejected a pay offer, according to Unite.
The ballot opened on Friday 1st May and will close on Thursday 21st May. If workers vote in favour, strike action could take place during the peak summer period.
That includes the World Cup, when many Scots are expected to travel abroad, and the Commonwealth Games in Glasgow from 23rd July to 2nd August.
The workers deal directly with passengers in airport security, processing people through checks before flights. Any action could lead to longer queues and delays at busy times.
Unite general secretary Sharon Graham said: “Unite has warned ICTS that our members at Glasgow Airport deserve a better pay offer than what is currently on the table.
“ICTS is a highly profitable company that can fully afford to make a decent pay offer. The company’s cavalier attitude and failure to make a fair pay offer has created this dispute.
“Unite will back our ICTS members every step of the way in their fight for better jobs, pay and conditions.”
Unite said ICTS (UK) Limited recorded profits of £7.6million in 2025, up from £4.4million the previous year.
Carrie Donoghue, Unite industrial officer, said: “Unite has made it clear that there should be a far better pay offer which reflects the critical role our members perform at Glasgow Airport.
“The reality is that the airport simply can’t operate without them.
“It is ICTS that is putting the travelling public at risk during an expected very busy summer due to the World Cup and Commonwealth Games.”
ICTS has been contacted for comment.
