Members of the Rail, Maritime and Transport Union (RMT) will begin industrial action from September 5.
The union claimed management had refused to engage seriously with its demands on pay, fatigue management, shift patterns and a reduction in the working week.
A separate dispute will also see RMT members on London’s Docklands Light Railway (DLR) strike from September 7.
Strike action: Sunday 7 – Friday 12 September ⚠️
– Sunday 7: Limited Tube service, ending earlier than usual. Please complete your journey by 18:00.
– Monday 8 – Thursday 11: Very limited or no Tube service, with no trains before 08:00. Please complete journeys by 18:00.

The strikes will see service impacts on the London Underground and DLR services.
Many travellers are now asking if the Elizabeth Line will be impacted by the strikes.
Transport for London (TfL) has since shared official advice related to the Elizabeth Line and other services.
Is the Elizabeth Line running during September Tube strikes?
Regarding the Elizabeth Line and if it is affected during the Tube strikes, TfL shared that it will have “normal service”.
However, they have warned that all other TfL services not affected by the strikes, including the Elizabeth Line, Overground, and trams, are likely to be “extremely busy” on strike days.
