The RMT union has suspended a strike by Tube workers that was due to begin at the weekend.
The union said nearly 60% of the original job cuts planned by London Underground have now been reversed ‘after three years of solid campaigning’, with 533 of the 953 jobs cut under former mayor Boris Johnson reinstated.
RMT general secretary Mick Cash said: ‘The fighting stance taken by RMT members since the jobs cull on our tube stations was first announced has reversed nearly 60% of those savage cuts.
‘That is a tremendous victory and a reflection of the resilience and determination of our reps and the membership right across London Underground.’
He added that the union would remain ‘eternally vigilant’ as it worked on implementation of the new staffing arrangements at the local level.
Current mayor Sadiq Khan said: ‘Like all commuters in London, I’m delighted that we have been able to get the tube strikes suspended.’
He also blamed Mr Johnson for the dispute, adding: ‘This shows what we can achieve by talking and engaging with staff.’
The RMT said it particularly welcomed the agreement to reopen control rooms and the guarantee of promotion into safety critical grades for some customer service staff.
