The Rail, Maritime and Transport (RMT) union has cancelled tomorrow’s planned strike.
The industrial action over pensions and benefits has been called off because London Underground cancelled scheduled engineering work due to take place at the weekend.
Therefore, the union believes that it has achieved its aims without needing to carry out the strike.
RMT General Secretary Bob Crow said: “The cancelling of the weekend’s engineering works schedule is a clear recognition by LU of the success of RMT’s previous action and as a result we have no need to proceed with this round of strikes as our objective has been met.
“Therefore the union is suspending the planned action.
“The dispute, over pensions and passes justice and equality with other LU staff, remains very much on and we will now be reviewing the tactics and the success so far which has been achieved as a result of the solidarity and determination of RMT members.”
The strike was due to affect the Jubilee, Northern and Piccadilly Lines from 6am tomorrow until 6am on Saturday.
The RMT union claims workers for Tube Lines, which maintains the network, should have had their pensions and benefits brought level with existing Transport for London (TfL) staff when the two merged in 2003.
Tube Lines says maintenance staff have retained their existing employment conditions and labelled the strike “unnecessary”.
