The RMT union called strike action on the Northern Line today (December 1) following one of its members being dismissed by London Underground after failing an alcohol breath test.

The strike has received little support from RMT members (only 45 of the 106 balloted voted for strike action), meaning that the Northern line is still running a good service during the rush hour.

“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,” Phil Hufton, LU’s chief operating officer said.

Extra trains are operating on the Wimbledon branch of the District Line to help customers in south London who may find it easier travelling from Wimbledon, and extra buses are operating on some routes.
