Hundreds of thousands of commuters will be hit by a double Tube strike after the RMT union announced a Central line walkout on the same day as industrial action on the Piccadilly line.
Workers on the Central line will strike for 24 hours on November 7 over a "comprehensive breakdown in industrial relations", the union said.
The union's members on the Piccadilly line are holding a strike on the same day following a similar dispute, threatening travel misery for Londoners.
RMT general secretary Mick Cash said: "Industrial relations on the Central Line have been at breaking point for some time now and the failure of the management to address the issues, and a conscious decision to up the ante by attempting to single out and pick off individual members of staff, has tipped the situation over the edge and has led to the announcement of strike action today.
"There is a growing culture on London Underground that revolves around refusing to employ enough drivers, bullying staff and expecting our members to pick up the pieces when the service breaks down.
"RMT members on the Central Line have made it clear that they have had enough and are prepared to stand up and fight for workplace respect and justice.
"Tube bosses are well aware of the level of anger on the job and it's down to them to take the situation seriously and engage in genuine talks around reaching a solution to the current disputes."
Nick Dent, Director of Line Operations for London Underground, said: "The strike action called by both RMT and Aslef on 7 November is totally unjustified. Our commitment to the safety of our customers and staff is absolute and something we will never compromise on.
"I urge the unions to call off this entirely unnecessary strike action which will only cause disruption to our customers."
Piccadilly line drivers also held two strikes last month in the row over industrial relations between the union and Transport for London.
