Is the London Overground affected by the May 2026 tube strikes?

"London is bracing for another week of strikes on the tube. Starting next Tuesday (May 19), London Underground drivers who are in the RMT union will walk out in two 24-hour strikes spread across four days. The drivers are protesting TfL's plans to implement a four-day working week. The RMT says that, under the plans, staff will work a five-day week's worth of hours in four days, increasing fatigue and compromising safety. TfL insists that the proposals are voluntary."
