Maintenance workers on London’s Elizabeth Line will stage a 24-hour strike from Friday night in a dispute over pay.

The Rail, Maritime and Transport union (RMT) said its members were being paid significantly less than similar positions across the network.

RMT general secretary Mick Lynch said: “It cannot be right that maintenance staff doing essential work keeping the Elizabeth Line running are being short-changed.

“The employer must make a decent offer on pay that reflects the vital work our members perform in order to avoid future strike action.”
