London Underground strike action related to a proposed four-day week plan is reported as being called off. Multiple outlets say Rail, Maritime and Transport (RMT) union members had been expected to walk out over plans that would introduce a voluntary four-day week for Tube drivers, with condensed working hours. The dispute centers on whether such arrangements should be adopted for staff. One report states that RMT members voted against the proposal, contributing to preparations for industrial action. Another account says planned strikes for consecutive days were initially scheduled to go ahead, with drivers expected to participate in a second series of walkouts. However, the same outlets then report that the planned strike dates are not proceeding, despite the earlier decision and the planned action being linked to opposition to the four-day week proposal. Across the reports, the focus remains on the labor disagreement over condensed-hours arrangements and whether drivers should take on a different pattern of working time. The reports do not provide detailed reasons for the cancellation beyond the context of the ongoing dispute.
