RMT Leads Six-Day Tube Strike Across London Underground

London commuters are facing significant disruption throughout September 2025 due to a week-long London Underground strike, which began on September 5 and is set to end on September 12 with a reduced service initially. The strike, organized by the Rail, Maritime and Transport Workers (RMT) union, centers on pay, fatigue management, extreme shift patterns, and prior agreements not being honored. RMT General Secretary Eddie Dempsey has urged Mayor Sadiq Khan to convene a summit to resolve the dispute, criticizing the collapse of industrial relations and warning of further action if no progress is made. Dempsey emphasized that the union members seek reasonable improvements rather than excessive demands and are open to negotiation. However, Mayor Khan and Downing Street have called for both sides to return to talks, with Khan indicating he cannot directly intervene, noting last year's pay rise was an exceptional measure. The ongoing strike has affected not only the Tube but also the Docklands Light Railway, with additional disputes looming over cleaners' pay and ticket office futures on the Elizabeth Line.
