RAIL union RMT is to step up its action against London Underground’s plans to impose all-night working without agreement.

Bosses are pressing ahead with London Mayor Boris Johnson’s reckless plan, despite united strike action by the Tube’s four unions — RMT, Aslef, TSSA and Unite.

A 24-hour strike brought the Tube to a standstill on Thursday July 9. Another 24-hour stoppage is planned for August 5-6.
Talks are being held between the unions, management and conciliation service Acas.

The unions say management proposals to pay staff extra for all-night working are totally inadequate and would benefit less than one-third of the workers.

RMT has imposed an overtime ban and, this week, accused bosses of breaching safety regulations to undermine it.

Members will take extra action from July 28. Drivers are being told not to bring trains into service if they do not believe they have been properly prepared and not to take part in any training or working practices not regarded as “normal.”

RMT general secretary Mick Cash said in a message to members: “We continue to try to resolve this dispute, but LU has failed to properly address our claim.

“Their current offer is totally divisive and they have completely failed to address the wider issues of your work-life balance caused by their reckless efforts to bulldoze through the introduction of night Tube.

“The offer was designed to buy off the minority to the detriment of the majority — over two-thirds of staff would not benefit from any payment for night Tube.

“Furthermore, there was not any commitment to ensure that other grades would get a payment as and when night Tube is rolled out across London Underground.

“The recent strike was rock solid and the ongoing overtime ban is having a drastic impact on their ability to run a
service.”

Unions are unhappy about pay and shift arrangements for the new all-night Tube service, which is due to begin on September 12.

Some 20,000 Tube workers took part in the July 9 strike.
