The planned strikes by London Underground drivers, set to disrupt services over two 24-hour periods this week, have been suspended by the RMT union. The action, which would have closed some tube lines entirely and caused widespread travel chaos, has been called off after the employer shifted its position. An RMT spokesperson confirmed that the union now has the opportunity to address members’ concerns over new rostering, fatigue, and safety issues, though the dispute remains unresolved.
Why the strikes were called off
The suspension comes after Transport for London (TfL) clarified that its proposed four-day week would be implemented on a voluntary basis. While the rival union Aslef, representing a slight majority of tube drivers, has already endorsed the plan, RMT members had opposed it. A letter from TfL to the RMT—confirming the voluntary nature of the trial—appears to have provided the union with enough flexibility to pause the strikes and continue negotiations.

Nick Dent, director of customer operations for London Underground, welcomed the decision, calling it “good news for London.” He emphasized that TfL’s voluntary four-day week proposal aims to balance improved work-life balance for drivers with reliable service for passengers. Further discussions with all trade unions are expected to follow.
What happens next?
While the immediate strikes have been averted, the underlying dispute over rostering and working conditions remains unresolved. RMT has made clear that further action—originally scheduled for June—could still proceed if no progress is made. The union has rescheduled potential strike dates to June 2 and 4, though these may be subject to change depending on negotiations.
TfL had previously warned of severe service disruptions, with some lines facing complete closures during the planned stoppages. The voluntary four-day week trial, if implemented, may ease tensions—but its success will depend on whether RMT members ultimately accept the terms. Meanwhile, Aslef’s endorsement suggests a growing divide between the unions, with drivers increasingly supportive of the proposal.
