Talks have resumed between London Underground and the RMT union to try to stop further strikes over a new rostering system.
RMT members have already taken two days’ industrial action on New Year’s Eve and earlier this week because they claim that the new rostering system is unsafe.
RMT general secretary, Bob Crow, welcomed the new round of talks.
“We are pleased that discussions have recommenced with London Underground to resolve all the outstanding issues relating to the dispute,” he said. “No further comment will be made until the talks conclude.”
The effectiveness of the strikes has been called into question after the RMT claimed widespread stoppages but commuters reported only limited interruption to their journeys.
