A series of 24-hour strikes by the RMT union involving London Underground drivers is planned in protest of a proposed four-day condensed working week, with the first strike scheduled for March 24–25 and further actions through May.

The disputes center on shift lengths, working-time arrangements, transfer and allocation processes, fatigue, and safety, amid plans to compress the week despite a majority of Train Operators rejecting the idea in referendums.

Around 1,800 RMT driver members are involved in the dispute, roughly 40–50% of Tube drivers.

TfL warns the strikes will seriously affect businesses and commuters and urges the action be called off, stressing that changes are voluntary and do not reduce contractual hours.

Alternative travel options during disruptions include bus and National Rail services, with e-bike hire schemes noted as popular during disruptions.

TfL has not issued an official comment yet, but planning notes emphasize preparing for disruption and providing options to reach airports via non-striking services.

ASLEF drivers are not striking, and non-driver RMT members are not taking part, limiting immediate information on exact service impacts.

A TfL spokesperson defends the four-day week as aimed at improving reliability and flexible deployment, without added costs, and says it would be voluntary for Bakerloo line drivers initially.

Context is provided by a timeline of prior major London Tube strikes, highlighting recent industrial action history.

TfL maintains the four-day week would be voluntary, with no reduction in contractual hours and the option for drivers to remain on a five-day pattern if they prefer.

TfL describes the strikes as unnecessary and notes ongoing discussions to implement a voluntary four-day week for Bakerloo line drivers only, preserving contractual hours and five-day options.

Historical context shows the last Tube strike occurred in September over pay and conditions, causing major disruptions.
