London Underground workers are set to go on a 48-hour strike starting 9pm on Tuesday October 14.
The Tube strike will end on Thursday 16 October at 8:59pm.
The Rail, Maritime and Transport (RMT) union said they are striking due to ticket office closures which will lead to further job cuts.
RMT general secretary Mick Cash said: “RMT negotiators have made every effort in the long-running talks to resolve a range of issues that impact on our members jobs, their pay and working conditions and the safety of the services that they provide to the travelling public.
“The cuts, currently being bulldozed through, would de-staff whole areas of the Tube system at a time of surging passenger demand and would make evacuation and other basic safety procedures a physical impossibility.
“The axing of ticket offices and station staffing grades would render the Tube a no-go zone for many people with disabilities and for women travelling alone. The cuts ignore the realities of life that we saw when services broke down last week and the recent surveys which point to an increase in violence and sexual assaults.
“RMT will not stand back and allow Government-driven austerity cuts to hollow out the Tube system and leave it as a dangerous shell. We are also fully aware that the current cuts are just part of a multi-billion pound attack that will include such lethal ideas as driverless-operation.
“The strike action next week is designed to force the mayor to instruct his senior officials to back away from this toxic cuts package and engage in serious and meaningful negotiations.”
Transport for London is on a mission to save £4.2bn by 2020 and is expecting to save £50m a year by closing ticket offices.
