Starting later this month, more than 2,000 members of security personnel across Terminals 3 and 5, as well as those working in campus security, will stage 31 separate days’ strike action.
The action will get under way on 24 June and run through to the August bank holiday weekend, with the strikes set to impact the Eid festival (28-30 June) and the start of the school summer holidays (21-24 July).
Airlines set to be impacted by the walkouts at Terminal 3 include Virgin Atlantic, Emirates, Qatar Airways, United Airlines, American Airlines and Delta Air Lines, while the action at Terminal 5 will mainly affect British Airways.
