London Underground workers will stage a series of strikes in the new year in a dispute over pay.
Members of the Rail, Maritime and Transport union (RMT) have voted overwhelmingly to take industrial action over a 5% pay offer.
Engineering and maintenance workers will be taking action over January 5/6, with no rest-day working or overtime until January 12.
London Underground control centre and power/control members will be taking action over January 7/8, and fleet workers will walk out on January 8.
Signallers and service controller members will take action on January 9 and 12 while all fleet, stations and trains grades will walk out on January 10.
RMT general secretary Mick Lynch said Tube workers who help bring “vast amounts of value” to the London economy were not going to put up with senior managers and commissioners “raking it in”, while they were given “modest below-inflation offers”.
He said: “The refusal of Transport for London to restore staff travel facilities and create a two-tier workforce is also unacceptable.
“Our members have made it clear that they are prepared to take action and we urge TfL to improve their offer to avert disruption in the capital.”
A TfL spokesperson said: “We are disappointed that RMT has announced strike action based on our full and final pay offer.
“We have been clear throughout our productive discussions with our trade unions that this offer is the most we can afford whilst ensuring that we can operate safely, reliably and sustainably.
“We encourage the RMT to engage with us to avoid disruption for Londoners at the start of next year.”
