The Rail, Maritime and Transport (RMT) union voted on Thursday to strike in two separate disputes over pay deals and proposed job losses.

The strike will affect most of Tube lines and will commence on 9 June at 7pm, if it does go ahead, and continue until the same time on 11 June.

It will bring the network, used by over 3 million passengers a day, to a standstill and could cost the London economy up to £100m.

The union has asked the mayor to intervene after a "total breakdown" of relations between them and London Underground, after LU had said the unions demands were "unrealistic". The mayor's office has responded by confirming that Transport for London (TfL) is ready to commence talks.

The RMT general secretary Bob Crow said, "RMT are in no doubt that this dispute has been deliberately provoked by managers who have gone out of their way to engineer confrontation."

"There has been a total breakdown of industrial relations and that's why RMT are calling for direct talks with London Mayor Boris Johnson in an effort to resolve the current dispute," he said"

The RMT said the ballot result was "overwhelmingly" in favour of strike action with 2,810 voting for and 488 against. London Underground hit back however, with chief operating officer Howard Collins saying that was "only 30%" of union members and that the union was "clearly out of touch with their membership", the BBC reports.

The union has accused London Undergound of refusing to abide by an agreement which ensured job security and ruled out compulsory redundancies which would put 3,000 jobs at risk. A five-year pay offer by London Underground has also been rejected as "unacceptable" by the union.

The BBC reports a spokesperson for the mayors office said, "They (RMT) have so far failed to engage with Transport for London (TfL) beyond issuing completely over-the-top pay demands."

"TfL are ready and waiting for talks with the RMT leadership and the RMT should do what they have so far refused to do and represent their members at the negotiating table. The mayor is adamant that the RMT cannot continue to wreak disruption on Londoners' lives with continuous threats of strike action," the spokesperson said.
