Plans have been announced for a Tube strike on the Central and Waterloo & City lines this week.
If it goes the ahead, RMT Union members will walkout for 24-hours from 9pm on Wednesday January 25.
There will be no service on the Waterloo & City line and on the Central line there will be no service east of Leytonstone and a reduced service on the rest of the line all day on Thursday January 26.
Transport for London say all other lines will not be affected by the action, but some services will be busier than usual.
RMT Union say the strike is over "cuts-led forced displacement of staff" and announced the walkout after a ballot strongly in favour of strike action and following the "failure of ACAS talks to resolve the dispute".
RMT general secretary, Mick Cash said: “RMT negotiators have made strenuous efforts through the ACAS machinery to resolve this dispute but the door has been slammed in our faces.
“Let us be in no doubt, if LU (London Underground) are allowed to get away with this move on the Central Line they will start shunting drivers around the combine at the drop of a hat regardless of the consequences.
"With massive budget cuts in the pipeline at LU this is a straw in the wind as to how the company expects to operate in the future.
“Staff across London Underground are angry and the company would be wise to recognise that.
"The action is on and RMT remains available for serious talks.”
London commuters experienced travel chaos as workers staged a 24-hour Tube strike earlier this month which caused chaos in the capital on Monday, January 9.
Following the news of a second strike this month, operations director for the Central line, Peter McNaught said: "We apologise to customers for the disruption they may experience due to this unnecessary strike.
"We have made all reasonable efforts to resolve this dispute with the RMT through talking through the issues with them, and we have minimised the number of employees affected from 30 to eight.
"We urge the RMT to engage with us to resolve this issue and to withdraw the strike action, which will only cause needless disruption to Londoners."
