Check-in staff and other workers at Heathrow took action after BA refused to reverse a 10% pay cut imposed during the pandemic despite the airline reinstating managers’ pay.

Unions have now struck a deal with BA that is being voted on by staff, with the ballot closing on 21 July.

The GMB union said those involved were “predominantly low paid women”.

It added: “Industrial action has been suspended after BA made an improved offer, which members will now vote on. If workers vote to accept the deal, the Heathrow strike will be called off.”

Nadine Houghton, GMB national officer, said: “Our members stood up for themselves and fought for what they were owed. 

“Not only have these predominantly women workers won pay improvements for themselves, but BA have now been forced to make this offer to the rest of their staff too.  

“GMB members organising and threatening strike action have forced British Airways to finally move on pay – something which is long overdue.  

“These are frontline workers facing harassment and in some cases abuse from customers daily. The least they deserve is fair pay.  

“They will now vote on whether to accept the new pay deal – which the GMB is recommending they do.”
