The RMT union has announced that tube staff will take strike action at Euston and Green Park stations on 3 June, if action is not taken against a ‘bullying manager’.

RMT says members at both stations have suffered years of intimidation, bullying and unjustified sackings of colleagues by a manager who, it says, has created a toxic atmosphere in the workplace.

Strike action is set for June 3 which coincides with the Queen’s Jubilee. The strikes will last the entire day and will affect Victoria, Jubilee, and Piccadilly line services at both stations.

Green Park is close to Buckingham Palace which will be a popular location for Jubilee celebrations in the capital. Euston mainland station is a key hub for long distance trains heading north out of London.

Mick Lynch, RMT general secretary, said: “Staff at Euston and Green Park tube have suffered years of sustained bullying and intimidation by a manager who has created a toxic working environment.

“The union has tried in vain to reason with management, but they now will not let local representatives be part of a review into dismissals at the stations, instigated by the manager in question.

“Our strike on 3 June will cause significant disruption to people wishing to celebrate the Queen’s Jubilee. However, if tube bosses do the right thing, and deal appropriately with the manager in question, we can find a just resolution to this dispute.”
