The RMT also announced that its members, including signalling and station staff, would walk out on different days between 1 and 8 November after rejecting a “wholly inadequate” pay offer.
The union said some progress was made in negotiations, but maintained that the current proposal left a large number of staff excluded from collective bargaining.
RMT general secretary Mick Lynch said: “London Underground’s pay offer falls short of what our members deserve. It threatens to remove collective bargaining for a growing portion of staff, pushing them into pay bands that are decided solely by management. This undermines our members’ rights and the core principles of fair negotiation.
“No trade union can accept any pay proposal where management decide which of our members gets a pay rise and those who do not.”
Strikes will start on 1 November by maintenance workers and continue with different union members including signalling and station staff from 6-8 November.
The RMT said about 10,000 of its members were involved in the dispute, adding that it remained ready to engage in talks – but that a “fair and fully consolidated” pay offer must be put forward.
