London - It's the peak of the European summer season and more than a million holidaymakers could face a summer of misery due to strikes at Heathrow Airport.
Unions have warned that Britain’s busiest airport could be "shut down" as part of industrial action over a pay dispute.
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.
Workers backed strikes in eight ballots.
The Unite union said it followed the rejection of an 18-month pay offer amounting to £3,75 (about R65) extra a day for the lowest-paid employee. It predicted the walkout "could potentially shut down the airport."
