The majority of UK public sector workers have been demanding a pay rise to keep up with soaring 9.2% inflation in the country, caused by the government's COVID-19 bailouts and the Ukraine crisis.
In December 2022, over 115,000 Royal Mail workers from the Communication Workers Union (CWU) took part in the industrial walkout and demanded an increase in salary. The UK authorities reportedly were going to grant the public workers an income boost starting from April 2023 when the new fiscal year begins.
Worker strikes have become more frequent in the UK, as soaring inflation rises 40 years peak record 11.1% in October. Ex-Prime Minister Liz Truss' failure to curb growing prices and reduce the budget deficit caused were successed by Rishi Sunak's government attempts to present financial plan.
