Security Guards at London's Heathrow Airport to Escalate Strikes Over Pay Into Busy Summer Months

LONDON (AP) Security guards at London's Heathrow Airport, Europe's busiest, will escalate their strike action over pay into the busy summer months, the U.K.'s largest trade union said Wednesday.

The Unite union said more than 2,000 of its members will walk out for 31 days from June 24 through to Aug. 27, a move that could wreak havoc for the millions of people going through Heathrow during the summer travel season. Security guards have already been striking in recent months, including during the Easter break and the coronation of King Charles III.

Unite is putting Heathrow on notice that strike action at the airport will continue until it makes a fair pay offer to its workers," Unite general-secretary Sharon Graham said. Make no mistake, our members will receive the unions unflinching support in this dispute.
