Heathrow airport could be 'shut down' this summer due to strike action
Heathrow Airport could be "shut down" this summer due to a series of strikes over a pay dispute, union Unite said.
More than 4,000 workers including security guards, engineers and drivers will walk out on July 26 and 27, and August 5, 6, 23 and 24. It comes after workers backed strike action in eight ballots.
