Strike action on the London Underground may continue from February 6 unless the dispute is solved, the RMT Union has warned.
The long-running dispute between the unions and Transport for London continues over ticket office closures and job cuts, with no immediate sign of a resolution.
The union carried out a strike on Monday with the TSSA, bringing travel chaos to London as several stations were closed and many lines ran a limited service.
Now RMT general secretary Mick Cash has said: "RMT members have shown this week that they will not stand by while safety is compromised on London Underground.
“RMT members on the London Underground stations see day in and day out the toxic impact of the job cuts programme and they are reporting mback that it is horrific. "
The RMT Union also said that a ban on overtime will continue.
Conciliation service Acas has stated that new talks will be held over the issue, the BBC reported. However, Transport for London has not yet responded.
