A strike called by Spanish air traffic controllers is expected to cause problems for holidaymakers by disrupting flights during the peak of the summer holiday season.
The strike, expected to begin on 18 August and continue for three days, could affect more than two million passengers travelling to and from Spain.
During a vote called by the air traffic controllers union USCA, which represents around 95% of the controllers, 98% voted in favour of industrial action, according to the Daily Telegraph.
The Spanish Government and 2,300 controllers are locked in a dispute over a government decree outlining changes to controllers’ working hours and reductions in overtime pay.
The striking workers, who earn £167,000 ($265,682) annually on average, claim they are being forced to work excessively long hours.
The Spanish Airlines Association has said the strike will lead to massive cancellations of bookings and may force holidaymakers to switch to destinations in other Mediterranean countries.
