Union Split Weakens London Underground Strike as Aslef Backs Four-Day Week

Transport for London's compressed four-day work week has fractured the Tube driver workforce along union lines. The RMT opposes the arrangement as a safety risk and has struck repeatedly since March. Aslef, representing a slight majority of drivers, supports it—and didn't participate. This division has allowed management to maintain partial service using Aslef members and supervisors, limiting strike leverage. The competing positions on flexible scheduling complicate resolution prospects.
