Up to 1,200 London Underground jobs may be cut as a result of ticket office closures, according to the Rail, Maritime and Transport (RMT) union. The union said it had received leaked details showing 144 ticket offices may close and only main terminals will retain full offices.
RMT General Secretary Bob Crow said mayor Boris Johnson had "ripped up" his manifesto pledge to halt the closures.
The mayor of London's office said no decision had yet been made.
In his 2008 manifesto London Mayor Boris Johnson, who also chair's Transport for London (TfL), pledged to "halt the proposed Tube ticket office closures, and ensure there is always a manned ticket office at every station".
RMT's Bob Crow: 'Stations become dens for criminals'
According to the RMT changes under Mr Johnson's £5bn savings programme may result in 1,200 job cuts.
Only the main terminals will retain a full ticket office function with smaller central stations opening ticket offices at peak times only, according to the RMT.
The remainder - 144 stations - would be reduced to ticket machines only, the RMT said.
"Boris Johnson was elected by Londoners on an explicit manifesto pledge to ensure a manned ticket office at every station," said Mr Crow.
"RMT challenges the mayor to stick by that pledge and demand the binning of this cuts plan or stand exposed as a hypocrite who rips up key manifesto commitments to the voters who put him into office.
"The job cuts planned for underground stations would leave passengers dangerously exposed in the event of an emergency and would ratchet up the dangers for the public, particularly women, travelling late at night."
A spokesperson for the mayor said Mr Johnson "has been absolutely clear - all London Underground stations will be properly staffed throughout their opening hours."
But job cuts were not ruled out by the mayor's office.
"The mayor has outlined on many occasions how ending duplication of roles, scaling down back office staff, consultants, and so on, will help to ensure that the vital upgrades to the Tube and the construction of Cross rail will be safeguarded," the spokesman said.
"These are very difficult economic circumstances, and bearing down on TfL expenditure is a necessity," he added.
