HEATHROW workers, including firefighters and security staff, are to hold the first in a series of strikes tomorrow.
Members of the Unite union are set to walk out for 24 hours in a dispute over proposed pay cuts.
They will strike again on December 14, 17 and 18 unless the row is resolved.
As many as 4,000 staff members are threatening to strike, including baggage staff, security staff, engineers and operation workers.
Unite said it had serious concerns about the safe operation of Heathrow during the action.
But the airport said it had contingency plans.
A Heathrow spokesman said: “The strike decision is very disappointing during the worst crisis to hit the aviation sector.”
Airports have faced a difficult year with passenger numbers plummeting due to coronavirus – numbers were down 82 per cent last month, and are expecting to be even worse this month due to the lockdown.
The strike could affect families opting for a last-minute 2020 holiday this winter, with destinations such as the Canaries or Dubai popular this time of year.
