Britain"s rail network faced major disruption again on Wednesday as staff walked out in a row over pay and conditions, the latest in a wave of industrial unrest as wages fail to keep pace with soaring inflation. The 24-hour strike by more than 40,000 members of the RMT and TSSA unions forced around half of Britain"s rail network to close, with train companies operating a much reduced timetable and some parts of the country having no rail service at all, Reuters reported. Network Rail urged passengers, including commuters, families heading off on summer holidays, and sports fans on their way to the Commonwealth Games in Birmingham which begins on Thursday, to only travel if necessary. Changing working practices during the coronavirus pandemic meant many office workers were able to opt to work from home. Strike action last month brought Britain"s rail network close to a standstill for three days and just last week some key lines running the length of the country were forced to close when record temperatures damaged the track. "Our members are more determined than ever to secure a decent pay rise, job security and good working conditions," RMT general secretary Mick Lynch said in a statement. "Network Rail have not made any improvement on their previous pay offer and the train companies have not offered us anything new." The RMT union said it had received an offer of a 4% rise, followed by a possible 4% the following year dependent on staff accepting changes to their contracts. Inflation in Britain is running at a 40-year high and is expected to reach double digits later this year, driven by surging fuel and food prices. Soaring inflation and more than 10 years of stagnant real wages have triggered Britain"s worst cost-of-living crisis since records began in the 1950s, exacerbating labour tensions across sectors including postal services, health, schools, airports and the judiciary. It has also become a point of contention in the race to replace Boris Johnson as prime minister, with the final two candidates, Liz Truss and Rishi Sunak, vowing to crack down on strike action. The government last week changed the law to make it easier for businesses to use temporary staff to minimise the impact of strike action. Ferry services to Cowes in the Isle of Wight will also be disrupted on Wednesday due to strike action, and a new train strike is expected on Saturday. — Agencies
