London Underground drivers on two lines are to stage a 24-hour strike from tonight (UK) over claims that industrial relations have broken down.
Members of the Rail, Maritime and Transport (RMT) union working on the Hammersmith & City and Circle lines will walk out at 9.30pm.
The union accused management of being “heavy handed”, including putting staff toilet breaks on a stopwatch, and a “flagrant disregard” for agreed policies and procedures.
RMT general secretary Mick Cash said: “This dispute is about the basic issues of protecting working conditions of our members and defending agreements from attempts to drive a coach and horses through them.”
Transport for London said there will be no Hammersmith & City line service and a very limited service on the Circle line from around 9pm and all day Friday.
