Union leaders have threatened on Thursday that they will “bring London to a halt” as pay talks collapsed, RMT leader Mick Cash warned of “all-out confrontation.”
Walkouts across London’s tube network could begin at the end of July that could affect four million people a day that use the Tube.
A Transport for London (TfL) spokesperson said, “We have made an offer to our unions that we believe is fair and affordable.
“We remain available for further discussions and have asked that ACAS help to facilitate these talks.
“We look forward to finding a resolution in order to provide certainty for our hardworking staff.”
TfL blamed the never-ending costs and delays to Crossrail and Brexit for the reasons they cannot pay any more, despite the union demanding “substantial” pay rises.
Cash said, “Nobody should under-estimate the sheer level of anger among London Underground staff at the moment.
“It is these facts which are driving us to all out confrontation, and which will bring London to a halt.”
