Security staff at Barcelona airport took industrial action today - causing long queues and missed flights.
Staff at El Prat airport were working to rule and deliberately taking the maximum of ten minutes to pass each passenger through security.
The industrial action during peak holiday season has caused around 1,000 people to miss flights at the airport in the past few days, airline bosses said.
Around 350 staff from the private firm Eulen Seguridad work at the airport controlling queues, operating scanners and searching passengers.
They want increased staffing levels and improved working conditions, saying they are stressed and work up to 16 hours a day.
Mediation between the workers and their bosses at Eulen, at the Catalonia Labour Tribunal, broke down yesterday.
Spanish media reported the staff are taking unofficial action including delaying passengers for ten minutes each as they pass through security.
And increased action, including short hour-long strikes at key points of the day, are expected to begin on Friday.
A spokesman for the Spanish airlines association Aceta said the action was “causing delays at security controls that are causing some companies to delay flights so they can wait for passengers stuck in queues.”
