Overview
- Members of the RMT walked out for 24 hours on Tuesday and again on Thursday, forcing full or partial suspensions on multiple Underground lines and leaving negotiations unresolved.
- TfL ran reduced services with no service on the Circle and Piccadilly lines and sections of the Central and Metropolitan lines, while Overground, Elizabeth line, DLR and buses carried heavy extra demand.
- Transport for London said roughly 60% of drivers came to work because Aslef drivers accepted the proposed voluntary four‑day pattern, allowing partial morning services to run.
- The union says the proposal is a 'fake' four‑day week that would lengthen shifts and risk fatigue and safety, while TfL says the change is voluntary, would not cut contractual hours and it wants to pilot the pattern.
- Acas‑mediated talks collapsed before the strikes and both sides plan further discussions next week with the RMT warning more action is likely if terms are not renegotiated and businesses brace for continued economic impact.
