The Rail, Maritime and Transport union (RMT) has said their members will start voting on Tuesday to take industrial action.
The RMT has said that they are not happy with the latest pay offer from London Underground and the union are also calling for improved facilities for all Tube workers.
RMT general secretary Mick Lynch said: “Tube workers who help bring vast amounts of value to the London economy are not going to put with senior managers and commissioners raking it in, while they are given modest below inflation offers.
“The refusal of Transport for London (TfL) not to restore staff travel facilities and create a two-tier workforce is also unacceptable.
“Our members will now decide whether to set a mandate for strike action over pay and we urge TfL to improve their offer to avert disruption to Londoners.”
