Thousands of people could face travel chaos at the end of June if a planned rail strike from the RMT (Rail, Maritime and Transport) Union goes ahead.

Members of the union at Network Rail and 13 train operators will walk out on June 21, 23 and 25, in the biggest outbreak of industrial action in the industry in a generation.

The RMT also announced another 24-hour strike on London Underground on June 21 in a separate row over jobs and pensions.

The strikes threaten widespread travel disruption during a number of major events, including concerts, test match cricket and the Glastonbury festival.

Glastonbury starts on June 22, while that week will also see England play New Zealand in a test match in Leeds, the British athletics championships in Manchester, and gigs in London’s Hyde Park by Sir Elton John (June 24) and The Rolling Stones (June 25).

There will also be a Commonwealth Heads of Government meeting in London on June 24 and 25 and it is Armed Forces Day on June 25.

The union said it will be the biggest strike on the railways since 1989.

Union members voted overwhelmingly for action last month in growing rows over pay and job losses.

The RMT said rail staff who worked through the pandemic were facing pay freezes and hundreds of job cuts.

RMT general secretary Mick Lynch said: “Railway workers have been treated appallingly and despite our best efforts in negotiations, the rail industry with the support of the government has failed to take their concerns seriously.

“We have a cost-of-living crisis, and it is unacceptable for railway workers to either lose their jobs or face another year of a pay freeze when inflation is at 11.1% and rising.

“Our union will now embark on a sustained campaign of industrial action which will shut down the railway system.”

Mr Lynch added that the union was “open to meaningful negotiations with rail bosses and ministers, but they will need to come up with new proposals to prevent months of disruption on our railways”.

The union said more than 50,000 railway workers will walk out on June 21, adding that the action will affect the national railway network for the entire week.

Andrew Haines, Network Rail’s chief executive, said the organisation was “doing everything we can” to avoid the strike action.

“There are two weeks until the first strike is planned. We will use this time to keep talking to our unions and, through compromise and common sense on both sides, we hope to find a solution and avoid the damage that strike action would cause all involved,” he said.

Transport Secretary Grant Shapps described the move as “incredibly disappointing”.
