Tube drivers on London’s busy Victoria Line will stage another 24-hour strike this week.
Members of the Rail, Maritime and Transport Workers’ union (RMT) based at the Seven Sisters depot will stop working from 9pm on Wednesday 20 May.
It is the second day of action in a month, in protest against the failure of London Underground to install safety equipment on tube trains to stop doors opening on the wrong side of the train when it arrives at a station.
The RMT is also alleging that members are being bullied, harassed and victimised, and has called for the reinstatement of a sacked driver.
RMT general secretary Bob Crow said: “We know very well the disruption that the action will cause, but we will not sit back while managers play fast and loose with train safety and while our members and activists are subjected to intimidation, bullying and victimisation.”
Transport for London (TfL) said the RMT should “stop the threat of disruption”.

About 600,000 passengers use the Victoria Line each day. The strike last month caused chaos as commuters scrambled to board other lines which had become severely overcrowded.
RMT is currently re-balloting nearly 10,000 members across London Underground and Transport for London for strike action in separate disputes centred on jobs, pay and breaches of disciplinary and attendance agreements. The ballots close on Thursday 28 May.
