A Tube strike is causing chaos across London with extremely limited services on the London Underground today.
Members of the Rail, Maritime and Transport union (RMT) and Unite are involved in a long-running dispute over jobs and pensions which has led to previous disruption due to industrial action.
Passengers are urged to check before travelling on Thursday with problems expected to continue into Friday morning due to the walkout.
Transport for London (TfL) said London Overground and DLR services may also be subject to last minute changes on Thursday, with London Trams running a reduced timetable.
Union members will mount picket lines outside Tube stations across the capital, with buses expected to be much busier than normal.
The RMT claims it offered to suspend the strike during talks but accused TfL of rejecting its proposals.
Glynn Barton, TfL’s chief operating officer, said no proposals to change pensions or conditions had been made.
TfL’s recent funding agreement with the government required it to develop options around pensions, but the organisation said if changes are to be made, there would be consultations before any decisions are made.
The RMT alleges it asked TfL to pause any job cuts and pension changes to give both sides time to negotiate a deal.
RMT general secretary Mick Lynch said: “TfL have missed a golden opportunity to make progress in these negotiations and avoid strike action.
“Our members are resolute in their determination to see a just settlement to this dispute, and they will continue their industrial campaign for as long as it takes.”
More than 1,000 Unite members will be on strike.
Unite general secretary Sharon Graham said: “TfL is needlessly attacking our members’ pay and pensions, which Unite simply can’t accept. The workers have the full support of their union in fighting these attacks. TfL must stop behaving like a race-to-the-bottom employer and put forward an offer that is acceptable to our members.”
