London Tube strikes confirmed

London faces four days of significant travel disruption as RMT union members begin a strike over proposed changes to working conditions.

Last-minute talks between Transport for London and the union collapsed on Sunday, leading to planned walkouts from May 19-22.

The dispute centers on a proposal to introduce a voluntary four-day week for Tube drivers, which the union claims would negatively impact services.

TfL has warned that several major lines will be completely suspended, urging commuters to seek alternative transport or work from home.
