Northern Line Drivers Go On Strike
London Underground said they were able to run a good service on Monday 1 December 2014 despite a strike by drivers.
Members of the Rail, Maritime and Transport (RMT) union walked out for 24 hours in a row over the sacking of a colleague.
Phil Hufton, London Underground's chief operating officer, said: "We have been clear from the outset that the RMT had absolutely no basis to take strike action after one of their members was dismissed for failing an alcohol breath test. This strike is inappropriate and will achieve nothing whatsoever.
"The strike has been poorly supported and our staff have come to work to help Londoners get to where they need to go. Station staff are also available across the network to help customers with their journeys."
RMT general secretary Mick Cash said: "Our members are standing rock-solid, shoulder to shoulder with their victimised colleague and, as we have said all along, the union is determined to secure a just and fair outcome to this dispute.
"Once again, the Transport for London advice to the public is contradictory and dangerous."
