RMT's general secretary Mick Lynch said they will "fight tooth and nail" to secure their member's demands.
He said: "Our members will never accept job losses, attacks on their pensions or changes to working conditions in order to pay for a funding cut which is the government's political decision.
"Tube workers provide an essential service to the capital, making sure the city can keep moving and work long hours in demanding roles.
"In return they deserve decent pensions, job security and good working conditions and the RMT will fight and tooth nail to make sure that's what they get."
The union, which represents 40,000 workers across Network Rail and 14 train operators, have already announced a national strike for March 16.
RMT members are also set to strike on March 18 and 30, as well as April 1.
And Network Rail members will walk out over March 16 and 17 March.
