The RMT today announced that further strike action will be called on London Underground totalling 48 hours in the dispute over pay and nightube. Drivers will not book on for any shifts from 9pm on Tuesday 25th for 24 hours, and then a further 24 hours from 9pm on Thursday 27th August. Other London Underground grades will take the same action but starting at 1830; for 24 hours on the 25th and 27th of August.

RMT General Secretary Mick Cash said:

“Our members the length and breadth of London Underground have made it clear that they are determined to protect their work/life balance and not fall into a trap where they will be forced to wreck their home lives in order to comply with the “rosters from hell” which have been drawn up to plug the staffing gaps in the Night Tube plans."

UNITE - London Underground’s assurances ‘ring hollow’ as Tube workers pencil in more strikes

London Underground’s failure to give cast iron guarantees over unsocial shift working on all-night Tube services will see over 400 Unite members once again taking strike action unless a breakthrough in talks can be found, it was announced today (Tuesday 11 August).

Commenting Unite regional officer Hugh Roberts said: “London Underground’s vague assurances over work/life balance and unsocial shifts ring hollow and don’t go far enough in giving our members the security they need to plan their home life over the long-term."
