The RMT union said its members were forced to take industrial action as London Underground "have refused to move one inch" over ticket office closures and claimed the operator had breached an agreement the groups had previously reached through Advisory, Conciliation and Arbitration Service (Acas).
Despite the spin from LU nothing that they are proposing is about 'modernisation'.
The current plans, closing every ticket office and axing nearly a thousand safety-critical jobs, is solely about massive austerity cuts driven centrally by David Cameron and his Government and implemented by Mayor Boris Johnson.
RMT could have recommended the suspension of this strike action if LU had responded positively to our proposal to halt the implementation of these savage cuts, stopping the dire impact they would have the length and breadth of London Underground.
