London Underground workers based at two Tube stations are to strike for one day over the Jubilee bank holiday in a row over bullying.
Members of the Rail, Maritime and Transport union at Euston and Green Park will walk out on Friday 3 June.
General secretary Mick Lynch said those based at the two stations had “suffered years of sustained bullying and intimidation by a manager”.
Transport for London (TfL) urged the union “not to take strike action”.
