London Underground and Transport for London (TfL) are shedding more than 1,000 back-office jobs, some of which will be IT jobs.
A consultation has begun on plans to reduce London Underground's workforce by 1,000, and Transport for London will see "several hundred" jobs go.
The positions will go from departments such as IT, finance, HR and legal, and the company hopes it will be able to shed the positions through recruitment freezes, using fewer contractors, and voluntary redundancies. "We hope to be able to achieve this without compulsory redundancies," a spokesman said.
The consultation at London Underground will last three months. Transport for London is currently carrying out a review into cutting its workforce. The spokesman said the company expects "several hundred" posts to go, but said "details will come forward at a later date."
The company insists the cuts are not related to the recession, but due to TfL's ten-year efficiency plan under which it hopes to make £2.6bn worth of efficiencies.
Frontline jobs at London Underground will not be affected.
TfL said, ""The underlying purpose of the review is to ensure that we have an organisation fit for purpose and designed to deliver the massive programme of change and improvement that we have embarked upon.
"While there are many details to work through we estimate that there will be a reduction in around 1,000 posts. Our priority is to seek to avoid redundancies by looking at temporary posts and by not filling current vacancies."
