Transport for London to cut 250 more jobs
Up to 250 jobs are to be cut on the underground following the takeover of maintenance firm Tube Lines.
Duplication of jobs and an efficiency drive will lead to managers, clerical and admin staff being laid off.
Tube Lines maintained the Jubilee, Piccadilly and Northern lines but its work was taken in-house this year.
The move comes as unions and transport bosses say they will hold talks to try to stop to a second strike over 800 job cuts.
Transport for London (TfL) said it was aiming to achieve the 250 reductions through cutting temporary posts and voluntary redundancies.
Andie Harper, chief executive of Tube Lines, said: "The acquisition of Tube Lines has given TfL greater flexibility to manage the vital programme of Tube upgrades, saving millions of pounds for London's fare and taxpayers.
"We are now beginning a consultation with staff and unions on the future shape of Tube Lines in the light of that acquisition."
But Bob Crow, general secretary of the Rail Maritime and Transport (RMT) union, said: "We have been warning repeatedly that transport in London is being lined up for a jobs massacre and this latest announcement is another bitter blow.
"We have no doubt that even heavier cuts are being cooked up behind the scenes. Our fight for jobs and services goes on."
Fresh talks aimed at averting more strikes by London Underground workers are to be held at the conciliation service Acas next week
Members of the RMT and Transport Salaried Staffs Association (TSSA) walked out for 24 hours last week, causing disruption to services.
The unions are fighting plans to cut 800 jobs. TfL said there would be no compulsory redundancies.
The unions have announced three further 24-hour strikes for 3 October, 2 November and 28 November.
