Tube strikes will hit the London Underground in May and June the Rail, Maritime and Transport union announced today.
The strikes will start at 9pm on Monday, May 16 with severe disruptions to services throughout that week, before the strike ends on 9pm on Friday, May 20.
Another week of strike actions will take place between 9pm on Monday, June 13 and 9pm on Friday, June 17.
Tube drivers voted for strike action over the sacking of two their colleagues, Alwyn Thomas and Eamon Lynch, by the TfL last year.
The union claims the drivers lost their jobs because they are union activists.
RMT general secretary Bob Crow said: “Eamon and Arwyn have been victimised for fighting cuts to jobs and services that would turn the Tube into a death trap.
“This vote for action sends out the clearest signal that workers who stand up for Tube safety will get the full support of RMT members.”
Manwhile, a TfL spokesman said: “It is absolute nonsense to suggest that these individuals were dismissed unfairly due to their union activities.”
“It is disgraceful that the RMT leadership is now choosing to ballot when both cases are still going through the employment tribunal process,” he added.
