Transport for London is warning that Underground services will start to be reduced from mid-morning, as RMT drivers prepare to walk out for 24 hours from midday. A second 24-hour stoppage is planned from midday on Thursday, and more have been called in May and June. The dispute is about proposals to offer a four-day working week to Underground drivers, who would work longer over the four days but have three days off a week.
