Millions of commuters face travel chaos across London as a six-day strike by Underground workers enters its most disruptive phase, with every Tube line affected and knock-on effects rippling across the capital’s entire transport network.
The walkout by National Union of Rail, Maritime and Transport Workers (RMT) members, which began on Friday 5 September, has escalated into one of the most severe transport disruptions in recent years. Transport for London (TfL) has warned of “little to no service” on all Underground lines from Monday through Thursday, forcing Londoners to seek alternative travel methods during one of the busiest periods of the year.
Initial disruption from control managers walking out on Friday has now expanded to include track access controllers, signallers, fleet staff, engineers and station workers in a coordinated rolling strike designed to maximise pressure on TfL management. The action is scheduled to continue until Thursday, 11 September, leaving the capital without reliable Tube services for nearly a full week.
When Will the Strike End?
The London Tube strike is scheduled to conclude on Thursday, 11 September 2025 at 11.59pm, with services expected to begin returning to normal from 8am on Friday, 12 September. However, commuters are warned that the first services on Friday morning will start later than usual, with full normal operations not resuming until late morning.
The phased nature of the strike means different groups of workers are walking out on successive days. Sunday 7 September saw Track Access Controllers, London Underground Control Centre staff, and Power Control and Emergency Response Unit members take action from 12.01am until 11.59pm, causing severe disruption with limited services running.
Monday 8 September brought the most comprehensive shutdown, with all Fleet Staff (except those involved in engineering vehicle operations and maintenance), Engineering, Stations and Train members striking for the full day. This pattern continues through the week, with Signallers, Service Control and Emergency Response Unit workers downing tools on Tuesday and Thursday.
Wednesday 10 September sees Fleet, Engineering, Stations and Trains members walking out again, ensuring sustained pressure throughout the week. The coordinated approach means TfL cannot maintain even limited services, as different critical roles are absent each day.
Collapse of Last-Minute Negotiations
The industrial action follows the dramatic collapse of eleventh-hour negotiations between TfL managers and the RMT on Wednesday 4 September. Despite TfL’s plea for a 24-hour reprieve to avert the strike, union chiefs refused to back down, making disruption inevitable from Sunday evening.
At the heart of the dispute lies a fundamental disagreement over working hours and pay. TfL has offered a 3.4 per cent pay rise, which it describes as “fair” and in line with offers accepted by the RMT across the rail industry. However, the union is demanding a reduction in the working week from 35 to 32 hours to address what it calls serious issues with “fatigue management and extreme shift patterns.
RMT General Secretary Eddie Dempsey explained the union’s position: “Our members are doing a fantastic job to keep our capital moving and work strenuous shift patterns to make sure Londoners get to their destinations around the clock. They are not after a king’s ransom, but fatigue and extreme shift rotations are serious issues impacting on our members’ health and wellbeing, all of which have not been adequately addressed for years by LU management.
Financial Stakes and Working Conditions
The dispute has exposed the significant pay and conditions currently enjoyed by London Underground staff. Tube drivers earn just over £70,000 annually, with advanced operators earning an average of £75,677. Station staff start at a minimum of £35,000 per year, typically rising to £46,000 within their first year of service.
Since 2020, Underground workers have received cumulative pay rises of approximately 25 per cent, including 8.4 per cent in 2022, 6.6 per cent in 2023, and 4.6 per cent last year. The current 3.4 per cent offer for 2025/26 would add to these increases.
Staff benefits include generous pension provisions, free all-zones Travelcards for themselves and a family member or friend, and a £400 payment for working Boxing Day. Station staff typically work 37.5 hours per week, qualifying them for 2.5 hours of additional leave weekly.
TfL insists that even a 30-minute reduction in the 35-hour week would cause chaos with staff rosters whilst doing virtually nothing to address the RMT’s concerns about fatigue. The transport authority estimates that reducing working hours would cost “tens of millions of pounds”, with a full reduction to 32 hours potentially costing “hundreds of millions”.
Mayor’s Non-Intervention Stance
London Mayor Sir Sadiq Khan has notably refused to intervene despite union requests for his involvement. His decision stems from criticism he faced after finding £30 million from City Hall reserves to avert an RMT strike in January 2024, which sparked accusations that he had “given in to union blackmail”.
Keith Prince, transport spokesman for the City Hall Conservatives, criticised the Mayor’s handling: “Khan has been absolutely useless in keeping his promise of ‘zero strikes‘ during his mayoral term.” The current crisis has effectively backfired on Khan, creating an expectation that TfL’s “final offer” will be improved if sufficient pressure is applied.
This political dimension adds complexity to the dispute, with the Mayor’s office stating: “Nobody wants to see strike action or disruption for Londoners. Strikes have a serious impact on London’s businesses and commuters. The Mayor continues to urge the RMT and TfL to get around the table to resolve this matter and avoid this industrial action.”
Impact on Services and Alternatives
Every single London Underground line is affected by the strike action, including the Bakerloo, Central, Circle, District, Hammersmith & City, Jubilee, Metropolitan, Northern, Piccadilly, Victoria and Waterloo & City lines. The Docklands Light Railway faces complete shutdown on Tuesday 9 and Thursday 11 September as part of a separate but concurrent dispute over pay and conditions.
However, some transport options remain available. The Elizabeth line, London Overground, trams and buses continue to operate, though all face severe overcrowding and potential service alterations. The Elizabeth line will not stop at certain stations during peak disruption times, particularly before 7.30am and after 10.30pm on Monday and Wednesday.
TfL’s Chief Operating Officer Claire Mann urged the union to reconsider: “Given the improvements we have recently put in place in response to concerns raised by our unions, we urge the RMT to call off this action, which will only disrupt Londoners. We want them to continue to engage with us and put our fair, affordable pay offer to their members.”
Cultural and Economic Impact
The strikes have already forced major events to reschedule. Post Malone postponed his two concerts at Tottenham Hotspur Stadium from 7-8 September to 20-21 September, with promoters Live Nation stating they could not approve the events without sufficient public transport. Coldplay similarly rescheduled their Wembley Stadium shows from 7-8 September to 6 and 12 September.
Businesses across the capital are bracing for significant losses as workers struggle to reach offices and customers cannot access shops and services. The Federation of Small Businesses estimates that previous Tube strikes have cost London’s economy up to £50 million per day in lost productivity and reduced consumer spending.
Trust Breakdown and Previous Agreements
The RMT claims the strikes stem not just from pay disputes but from TfL’s failure to honour previous agreements regarding staff travel arrangements and working conditions. Union sources describe an “atmosphere of distrust” where members feel “no one is listening to them”.
An RMT spokesperson told reporters: “The public statements from TfL have been disappointing and intransigent. We remain open to talks and are awaiting a revised offer.” The union particularly objects to TfL’s refusal to consider any reduction in working hours, even suggesting that “even a small cut in hours would take the pressure off.
TfL maintains it has made progress on previous commitments and recently implemented improvements in response to union concerns. Nick Dent, TfL’s director of London Underground customer operations, posted a video message to staff stating that the RMT’s demands for reduced working hours were “neither practical nor affordable.
Public Advice and Travel Alternatives
Transport authorities are urging Londoners to check before travelling and consider walking or cycling where possible. Those who must use public transport should allow significant extra time for journeys and expect extreme crowding on all available services.
TfL recommends using its journey planner to find the fastest routes during the disruption. Roads are expected to be significantly busier than usual, with increased congestion likely throughout the strike period. Some Underground stations may close entirely, affecting nearby Overground and Elizabeth line services that normally stop there.
Commuters are advised that all journeys on Sunday should be completed by 6pm, as services will end early. From Monday to Thursday, those needing to travel should prepare for severely limited options and potentially lengthy delays.
Looking Ahead
As the strike continues, pressure mounts on both sides to find a resolution. The RMT has indicated it might compromise, with union sources suggesting that “even a small cut in hours would take the pressure off”, hinting at potential movement from their 32-hour week demand.
However, TfL remains firm that the 35-hour week is non-negotiable. One senior official stated bluntly: “We are not going to go below 35 hours. It’s unaffordable.” This impasse suggests the current strike may not be the last, with the potential for further industrial action if no agreement is reached.
The dispute highlights broader tensions in London’s transport network about work-life balance, fair compensation, and the sustainability of public services. With staff retention rates high and vacancies oversubscribed, TfL argues its current offer is already industry-leading. The union counters that the unique demands of keeping London moving 24/7 require exceptional consideration for worker welfare.
As Thursday’s deadline approaches, millions of Londoners continue to face daily disruption, with the economic and social costs mounting. Whether this pressure will force a breakthrough in negotiations remains to be seen, but for now, the capital’s transport arteries remain severely constricted, testing the patience and resilience of all who depend on them.
