AIR traffic control staff working in Whiteley and Swanwick were due to be among protestors in London today.
Staff at the National Air Traffic Services were to go to the Department for Transport over plans to slash costs.
More than 2,000 postcards completed by members of Prospect and PCS unions will be handed to a representative of the UK government’s aviation minister, Simon Burns.
Under the Single European Skies proposals, the European Commission wants to halve Air Traffic Management costs by 2020. NATS is the UK’s largest provider of air traffic control services.
Emily Boase, Prospect national secretary, said: ‘The UK is one of the most efficient providers of air traffic control services, with the least delays in Europe.
‘All this will be put at risk if the commission’s proposals are carried through.’
Jeremy Gautrey, PCS Aviation Group Secretary, added: ‘There is no bigger risk to safety and service delivery in air traffic than cuts to air traffic management staff.
‘Cuts in staff and forced redundancies will be met robustly with industrial action by ATM workers across Europe.’
