Tube passengers face strike chaos

Millions of London Underground passengers were today warned of travel chaos after union leaders said a three-day strike by Tube workers will definitely go ahead this week.

The Rail Maritime and Transport union said more than 2000 of its members will walk out at 6pm tomorrow in a row linked to the collapse of the maintenance giant Metronet.

The RMT and other Tube unions are seeking guarantees that there will be no job losses, forced transfers or pension cuts. The RMT said that Metronet and its administrator had failed to give the "unequivocal" guarantees on jobs, transfers and pensions it was seeking.

London's mayor, Ken Livingstone, has written to all the unions stating that they have been given all the assurances they have been requesting and that the strikes should not go ahead.

RMT general secretary Bob Crow said today: "There has been no contact over the weekend from Metronet or the administrator so as far as we are concerned the strike will definitely go ahead."

The dispute involves maintenance workers and the RMT has predicted that the Tube network will "grind to a halt".
