Prepare passengers face additional disruption this summer time after members of the RMT rail union voted overwhelmingly for additional strike motion.

A poll of members working throughout 14 prepare working corporations “massively reaffirmed a mandate for additional strike motion”, the union mentioned on Thursday, with 90% of votes forged in favour of holding extra strikes over the subsequent six months.

The union’s chief, Mick Lynch, described the outcome as a “de facto referendum” on the dispute with a mean turnout of practically 70% in every firm.

“It’s clear from these outcomes that members are usually not ready to simply accept a pay provide primarily based on mass job cuts and main assaults on their phrases and situations,” Lynch mentioned.

“This sends a transparent message to the employers that the large anger amongst rail staff could be very actual and they should recognise that truth, face actuality and make improved proposals. They should get across the desk with RMT and negotiate in good religion for a greater deal for rail staff.”

Unions concerned in disputes should reballot their members each six months to legally proceed with industrial motion.

The following 24-hour strike is deliberate for Saturday 13 Could, the day of the Eurovision tune contest closing.

It follows the breakdown of talks final month. On the time, Lynch mentioned the Rail Supply Group (RDG) had been “pressured” by the federal government to renege on a 9% provide the union had been contemplating for a number of weeks, by making the primary yr’s pay deal contingent on withdrawing its mandate for strike motion.

“The RDG is now saying they might solely implement the first-year fee of 5% if the union terminated its industrial mandate – that means no additional strike motion might happen,” Lynch mentioned.

Earlier this week, the transport secretary, Mark Harper, criticised rail unions over the 13 Could strike.

Harper mentioned rail staff ought to work “in solidarity” with Ukrainian railway employees who’ve been killed, as a substitute of “cynically focusing on” Eurovision, which was gained by Ukraine final yr.

The prepare drivers’ union Aslef can also be planning to strike, on 12 Could. It not too long ago rejected a pay provide of 4% a yr for 2 years, describing the proposal as risible on condition that inflation is at 10%.

Additional drivers’ strikes shall be held on 31 Could and three June, the day of the FA Cup closing, when many followers shall be travelling from north-west England to London to see two Manchester groups play at Wembley.
