Drivers on the London Underground are to strike for two days next month in a row over new timetables.

The Rail, Maritime and Transport (RMT) union said its members will walk out on June 6 and 14, claiming the new timetables "ride roughshod" over rostering agreements.

Aslef members have co-ordinated their industrial action for the same day, meaning the District Line and Jubilee Line will be affected on commuter days with the first strike on a Wednesday and the second the following Thursday.

General secretary Mick Cash said: "It is outrageous that Tube managers are trying to bulldoze through timetable changes without agreement that ride roughshod over existing rostering agreements.

"It is symptomatic of a management that is out of control and hell-bent on imposing change through diktat rather than through the established negotiating machinery.

"Drivers are angry at the impact on work-life balance and rightly see this move as the thin end of a very long wedge that could see processes and agreements unilaterally shredded by Tube bosses.

"There's time for Tube management to reverse the imposition of these changes and to start talking seriously with the unions rather than wading in with the big stick."

It is the latest in a long list of disputes between the management and unions and comes five weeks after drivers walked out in a protest over the sacking of a colleague who reportedly drove through three red lights.
