At six UK airports, passport control employees are on strike seeking higher wages.

Long delays for travelers at UK airports followed the departure of Border Force officers as part of the most recent nationwide public sector strikes.

According to the Public and Commercial Services Union, more than 1,000 passport control employees are anticipated to walk out on the opening day of a strike over salary that is likely to extend till the New Year (PCS).

In the largest wave of industrial action over pay and conditions in Britain in decades, the walkout is the most recent addition to strikes by nurses, paramedics, and workers in the train and postal sectors.

After stoppages, the administration declined to raise wages as a result of years of stagnant pay and a cost-of-living problem that has seen inflation reach around 11%.

The PCS-organized walkout is the first of eight that will take place at six UK airports between this Friday and January 1.

In light of the cost-of-living problem, more than 1,000 Border Force officers are anticipated to walk out at six airports.

At Heathrow, Birmingham, Cardiff, Gatwick, Glasgow, Manchester, and the southern coast port of Newhaven, the government has hired members of the military services and civil workers to staff passport booths.

Many Border Force staff, according to PCS general secretary Mark Serwotka, are having difficulty keeping up with rising living expenses.

"45,000 of our members are collecting in-work benefits, and 40,000 of them use food banks. They are the poor who are still employed, he added, adding that the conflict also involved pensions and job security.
