London Underground drivers are to stage a series of 24-hour strikes in a dispute over working arrangements, the Rail, Maritime and Transport (RMT) union has announced.
A series of walkouts will begin on 26 November, in opposition to plans to introduce four-day working weeks.
Further strikes are planned for 17 December, 19 December, 4 January, 6 January, 17 February, 23 February and 25 February.
The union says drivers will face longer hours behind the wheel and longer days, but Transport for London (TfL) said its proposal for a four-day working week was voluntary and would mean drivers work fewer hours overall.
