The RMT union suspended planned strikes on the London Underground scheduled to begin Tuesday, May 19, following last-minute talks with Transport for London (TfL) on Monday, May 18 [1, 2, 3, 4]. The strikes, originally set to run from May 19 to 22 and again on June 16 and 18, were called off after the employer shifted its position, allowing further discussion of workers' concerns [1, 3, 4].

The core dispute revolves around TfL’s voluntary proposal to introduce a compressed four-day working week for Tube drivers, involving longer shifts over fewer days [1, 2, 3, 4]. While ASLEF, a rival rail union, supports the voluntary four-day week as a way to improve work-life balance and service reliability without reducing contractual hours, the RMT union opposes it [1, 2]. The RMT cited concerns about fatigue, safety risks, and the imposition of new rosters that could worsen working conditions [1, 2, 3, 4].

An RMT spokesperson said, "At the 11th hour the employer has shifted its position, allowing us to further explore our members’ concerns around the imposition of new rosters, fatigue and safety issues. The dispute is not over, and more strike action will follow if we fail to make sufficient progress" [1]. The union warned that new strike action would occur if negotiations stall [1, 4].

TfL confirmed the proposal is voluntary and aims to benefit drivers and improve service reliability [1, 2, 3, 4]. They also said strikes would reduce tube services and possibly shut some lines on strike days. However, other public transport such as the Elizabeth line, DLR, London Overground, buses, and trams are expected to operate normally but could face overcrowding [3].

The RMT has scheduled fresh 24-hour strikes for June 2 to 3 and June 4 to 5, with action due to proceed if no resolution is reached by then [1, 3, 4]. Previously planned strikes for June 16 and 18 have been canceled following the suspension of May strike days [1, 3, 4].

As of today, May 19, London commuters will avoid the disruption originally expected this week but face uncertainty with the prospect of multiple strike days in early June.
