RMT members working for 14 train companies will stage a fresh strike on 2 June in their long-running dispute over pay, jobs and conditions, the union announced.

The strike on 2 June will see 20,000 railway workers in catering, train managers and station staff all take action, affecting train services throughout the country.

The RMT said it found the Rail Delivery Group’s previous offer and associated conditions “unacceptable”.

“Despite contact between the parties since the strike on 13 May, no new proposals have been formulated for the RMT to consider,” the union tweeted today.

RMT general secretary Mick Lynch said: “The Government is once again not allowing the Rail Delivery Group (RDG) to make an improved offer that we can consider.

“Therefore, we have to pursue our industrial campaign to win a negotiated settlement on jobs, pay and conditions.

“Ministers cannot just wish this dispute away,” Mr Lynch added.

“They underestimate the strength of feeling our members, who have just given us a new six-month strike mandate, continue to support the campaign and the action and are determined to see this through until we get an acceptable resolution.

“The Government now needs to unlock the RDG and allow them to make an offer that can be put to a referendum of our members.”
