Fresh talks will be held Monday (August 10) in a bid to resolve the dispute over the Night Tube services which has already led to two days of shutdown.

The four unions protesting over the imposition of new rosters for the service which is due to begin on September 12 will sit down with London Underground management in talks chaired by the conciliation service Acas.

The RMT, Aslef, Unite and TSSA say they are concerned about the “work-life” balance of Tube staff who will service the weekend 24 hour lines, including the Jubilee. LU management has increased pay and bonuses and given assurances over the level of night work required.

If nothing is resolved, unions have said they will call more strikes, possibly for 48 hours at a time, while the Mayor of London Boris Johnson has already conceded that the start date may have to be delayed to accommodate the fractious dispute.
