Talks between TfL and RMT have broken down and a Picadilly Line strike will start at 1pm tomorrow (26th September).
The action will last until Friday though a full service will only resume on Saturday.
The RMT claims that progress has not been made on Service Control relationships with drivers problems at Arnos Grove depot still remain. They also state that plans to recruit more drivers for the line have been cut back.
TfL is battling a £700 million a year cut in finances from central Government enacted by George Osborne in his last budget in 2015. The same George Osborne now editing the Evening Standard, and complaining of cuts their editor implemented.
Mayor Sadiq Khan has also initiated a fares freeze costing at least £50 million a year. Opponents state this is hurting London transport, but supporters state it is arresting declines in usage and helping with congestion, and fares had already risen to a high level compared to comparable European cities.
