Security staff working at London Heathrow have cancelled a series of planned strikes this summer after agreeing to a pay deal with the airport.

The Unite union, which represents 2,000 workers at Heathrow’s Terminal 3 and 5, originally planned to hold industrial action on 31 days between late June and the end of August during the busy summer peak season for travel.

The union had already cancelled the first planned two-day strike on 24-25 June after receiving the new pay offer from Heathrow, which workers have now voted to accept. The deal gives security workers a pay rise of between 15.5 per and 17 per cent.

Sharon Graham, the general secretary of Unite, said: “This was a hard-won victory which demonstrates what can be achieved when workers stand together and take action together. 

“The pay deal at Heathrow is a further demonstration of how Unite’s complete focus on jobs, pay and conditions is having direct benefits for its members.”

A Heathrow spokesperson added: “We are pleased to confirm Unite members have voted to accept a two-year above-inflation pay deal, ending the current dispute and allowing the strikes to be called off.

“We can now move forward together and focus on delivering an excellent summer for our passengers.”
