TUBE workers are set to ramp up their industrial action over job cuts and ticket office closures, RMT revealed yesterday.
The transport union says the dispute will be escalated from February 6 unless a settlement is reached.
More talks are planned on Monday, through conciliation service Acas, between London Underground, RMT and the white-collar TSSA.
The unions want jobs reinstated and ticket offices reopened, saying cuts agreed by former London mayor Boris Johnson which have already led to 838 job losses are going too far.
RMT general secretary Mick Cash said: “RMT members have shown this week that they will not stand by while safety is compromised on London Underground off the back of cash-led cuts to staffing levels that the union has warned would have a serious, lasting and corrosive impact for staff and passengers alike.”
