Rail workers are set to strike in a dispute over pay, jobs and conditions which threatens travel chaos as the summer holidays continue.

The strike will take place on Wednesday, July 27 and it will see members of the Rail, Maritime and Transport union (RMT) at train companies and Network Rail walk out for 24 hours.

Union leaders announced the news after they rejected Network Rail’s new offer, describing it as “paltry”.

The offer was for a 4% pay rise backdated to January, another 2% next year and a further 2% conditional on achieving “modernisation milestones”.

Rail strike to take place in July

The RMT said it has yet to receive a pay offer or guarantees over job losses from the train operating companies (TOCs).

The RMT said it will be consulting other unions that have delivered mandates for strike action in the coming days, amid talk of co-ordinated walkouts.

Members of the drivers’ union Aslef and the Transport Salaried Staffs’ Association (TSSA) at train companies have backed industrial action in recent days.

RMT general secretary Mick Lynch said: “The offer from Network Rail represents a real terms pay cut for our members and the paltry sum is conditional on RMT members agreeing to drastic changes in their working lives.

“We have made progress on compulsory redundancies, but Network Rail are still seeking to make our members poorer when we have won in some cases double what they are offering, with other rail operators.

“The train operating companies remain stubborn and are refusing to make any new offer which deals with job security and pay.

“Strike action is the only course open to us to make both the rail industry and Government understand that this dispute will continue for as long as it takes, until we get a negotiated settlement.

“The public who will be inconvenienced by our strike action need to understand that it is the Government’s shackling of Network Rail and the TOCs that means the rail network will be shut down for 24 hours.”

The RMT held three strikes last month which crippled services across the country.
