Around 70 members of the union Unite working for special services company OCS Group have voted by 95% in favour of taking strike action on 6 and 11 July.
“The emphatic mandate in support of strike action should send a clear message to OCS - it’s time they put an increased offer on the table in new negotiations,” said general secretary Sharon Graham.
Her words were echoed by Unite industrial officer Pat McIlvogue, who called the situation disappointing, especially as other industrial disputes at the airport had been settled.
“Our members have been left with no choice but to take this step,” he added. “It will undoubtedly hit the summer schedule at Glasgow Airport and the blame for any disruption will be entirely the company’s.”
A Glasgow airport spokesperson told TTG the hub was in discussions with OCS Group to ensure contingency plans were in place.
