Hundreds of thousands of air passengers face possible delays today as Border Force workers become the latest to go on strike.
More than 1,000 employees will walk out, affecting passport control desks at Heathrow, Gatwick, Birmingham, Cardiff, Manchester and Glasgow airports, as well as the port of Newhaven in East Sussex.
The strike will last until early on Boxing Day, before another round from 28 December until early on New Year’s Eve.
More than 10,000 flights are scheduled to land at those airports during those times and more than 250,000 passengers arriving on Friday have been warned to expect delays.
The airports said that most departing flights would not be affected, although some arriving passengers – particularly those who cannot use eGates – could face delays.
Royal Mail employees will also be on strike today, their fifth day of action this month, in what Royal Mail said was a “cynical attempt to hold Christmas to ransom”.
The company has estimated that the strike, which will continue on Christmas Eve, has already cost it £100m.
National Highways workers in London and the South East will continue their four-day walkout that started on Thursday.
The workers, who plan, design, build, operate and maintain the roads, are following action by colleagues in Yorkshire and the Humber, northwest and northeast England.
Hundreds of thousands of workers are striking over winter as unions seek pay rises in line with the rate of inflation to help shield their members from the cost of living crisis.

Further January strikes for NHS workers
Earlier this week, NHS staff were on strike, with nurses walking out on Tuesday and ambulance workers following them on Wednesday.
Pat Cullen, head of the Royal College of Nursing, said on Thursday that if she did not hear from Health Secretary Steve Barclay by the end of the day, she would announce further January strikes dates.
“The public is clear – as am I – that the way to avoid further strike action is for the government to stop prevaricating and repeating the same tired lines and step up to holding meaningful negotiations with me,” she said.

Ambulance workers, represented by Unison, have already announced further strikes, with workers in London, Yorkshire, the North West, North East, and South West walking out on 11 January and 23 January.

Members of the GMB union at nine ambulance trusts are also preparing to strike on 28 December, while 1,000 union members in the Welsh Ambulance Service are set to announce strike dates in the new year.
Unison general secretary Christina McAnea said: “It’s only through talks that this dispute will end.”
