Tube staff in the RMT Union have threatened to walk out of Euston and Green Park stations on Friday June 3 over bullying allegations and a “toxic working environment”.
The strikes will last the entire day and will affect Victoria, Jubilee and Piccadilly line services at both stations.
Transport for London expect to keep both stations open, despite the planned action.
National Rail services at Euston will not be affected.
RMT general secretary Mick Lynch 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 June 3 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.”
The two stations are key for those attending celebrations near Buckingham Palace and those travelling into London from elsewhere in the UK, particularly the north west.
The capital is expecting a huge influx of tourists as the Queen celebrates her 70th year on the throne.
A TfL spokesperson told the Evening Standard: “We hold our people to high standards and ensure everyone is treated fairly.
“We're aware of this dispute and are carrying out an urgent review in a bid to resolve it.
"We have had a number of meetings with the RMT and are urging them not to take strike action and to continue working with us to find a resolution.”
