The United Kingdom is facing a new wave of strikes sparked by the cost of living crisis caused by high inflation and a deteriorating economy.
Meanwhile, union leaders warned of a "significant escalation" in public sector strikes if wages did not improve.
Today, Friday, workers in the health sector in Britain announced a new wave of strikes next January, indicating that their dispute with the government over wages and working conditions will continue in 2023.
The new strike dates will put more pressure on the publicly funded National Health Service, which is already suffering from a shortage of staff and record delays in providing services.
For his part, British Prime Minister Rishi Sunak told reporters that he was "disappointed" with the disruption and disruption caused by the strikes and added that he was trying to "take sound decisions in the long term for the country in the interest of all".
Meanwhile, General Secretary of the Trade and Public Services Union Mark Sirotka told the BBC on Friday that "there will be a massive escalation in public sector strikes if wage offers do not improve".
He added, "We can continue with these strikes even after Christmas ... and it may also continue until next May, and we will support this measure if we have to."
As border staff at the country's airports joined the strikes on Friday, the industrial strike - which will continue between Friday and next Monday - and again - from Wednesday to Saturday - will have a negative impact on London Heathrow and Gatwick airports as well as Birmingham, Cardiff, Manchester and Glasgow airports.
The railway workers' strike - which began in the summer - is still going on, and Royal Post employees will also strike, including members of the Communications Workers' Union, who collect parcels and letters, and then sort and deliver them.
In the context, the Royal College of Nursing announced new strikes by nurses in England on January 18 and 19.
"I would not like this row to drag on, but the Prime Minister has left us no other choice," said Pat Cullen, general secretary of the Royal College of Nursing, on Friday.
For weeks, Britain has witnessed an escalating wave of strikes in several sectors, most notably the sectors of ambulance drivers, forcing the government to seek the assistance of hundreds of army soldiers to drive ambulances, instead of its original crews on strike.
