Yesterday Tube Lines, which maintains the Jubilee, Northern and Piccadilly lines, and the RMT met at ACAS (Advisory, Conciliation and Arbitration Service) to try to resolve this issue through constructive discussion.
Unfortunately the RMT leadership have not agreed to suspend their action, which is completely unnecessary and will not achieve anything. Since becoming part of Transport for London all Tube Lines’ employees have kept their existing terms and conditions of employment.
The RMT's ballot showed that less than 44 per cent of its members voted in favour of strike action.
We urge the RMT leadership to return to discussions, and we remain ready to continue such discussions at any time to try and avert the strike.
Should this industrial action go ahead, we expect it to have no significant effect on Tube services.
We have well practised contingency plans in place to ensure that the essential maintenance required on the railway can either go ahead as planned or can be rearranged.
We do not and will not put passenger or staff safety at risk.
Maintenance staff on three tube lines are entering their third day of strikes today.
A strike affecting the Jubilee, Northern and Piccadilly lines goes ahead from 4pm.
Union bosses have forecast "widespread" disruption, as workers who maintain and upgrade tube lines go on strike next week.
