Passengers at United Kingdom airports experienced long delays after Border Force officers walked out as part of the latest strikes of public sector workers across the country.

More than 1,000 passport control staff are expected to walk out on the first day of a strike that is planned to last until New Year over pay, according to the Public and Commercial Services Union

The walkout is the latest addition to strikes of nurses, paramedics, and workers in the rail and postal sectors in the biggest wave of industrial action over pay and conditions in Britain for decades.

Following stoppages, the government refused to increase pay following years of wage stagnation and a cost-of-living crisis that has seen inflation running at nearly 11 percent.

The strike, organised by the PCS, is the first of eight planned between Friday and January 1 at six UK airports.

The government has drafted in armed forces personnel and civil servants to operate passport booths at the airports

PCS general secretary Mark Serwotka said many Border Force employees were struggling with the cost-of-living crisis.
