Around 2,000 members of the Unite union, who work at Heathrow’s Terminal 3 and 5, had been due to walk out on 31 days from late June to the end of August but this action will not now go ahead.

The union had already called off the first planned two-day strike for this weekend (24-25 June) after receiving a new pay offer from Heathrow earlier this month, which workers have now voted to accept.

Unite’s general secretary Sharon Graham 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.”

The deal will see security workers at Heathrow receive a pay rise of between 15.5% and 17% “depending on their pay banding position”.

A Heathrow spokesperson said the end of the industrial dispute would allow the airport to “focus on delivering an excellent summer for our passengers”.
