Transport for London aim to make up cash shortage with £2.4bn savings this year

Unions have vowed to strike after London Underground's plans to cut 1,000 jobs.

The TfL subsidiary is to address the company's financial situation this year, affecting what it called “non-operational areas” including finance and administration. The organisation, which employs, 20,000 is trying to save £2.4bn this year.

RMT general secretary, Bob Crow, said: “Any attempt to impose compulsory redundancies on our members will be met with a ballot for industrial action."

The firm said no Tube drivers or front-line staff would be affected by the job losses. It said it would attempt to fire temporary staff and not fill vacancies.

TfL earlier warned that it was facing a cash shortage as it sought to cope with Crossrail and a funding shortfall in the Tube network.
