RMT Tube drivers strike again in June over four-day week plan

In early June 2026, Tube drivers belonging to the RMT union staged another round of strikes on the London Underground. It was part of a continuing dispute over a compressed four-day working week proposed by Transport for London (TfL), the capital's transport authority.

TfL said the new pattern was voluntary and would not change drivers' contracted hours. It argued the plan would improve work-life balance. The RMT disagreed. It said the arrangement would mean longer shifts and more fatigue, and it objected to the change being introduced in this way.

The dispute was complicated by the position of Aslef, the other main drivers' union, which accepted the proposals. That left TfL able to say that a large part of its driver workforce backed the plan, while the RMT continued industrial action. TfL described the walkout as disappointing after talks held through the conciliation service Acas.

The June action added to earlier strikes in the spring and caused disruption to services across the network. It set the pattern for later rounds of walkouts in the same dispute.
