“The action will continue every weekend until 18 December, unless an agreement is reached. Here are the strike times in full: 4.30am 26 November – 4.29am 27 November (Central, Jubilee, Northern, Piccadilly and Victoria lines) 8.30pm 27 November – 4.29am 28 November (Central and Victoria lines) 8.30pm 3 December – 4.29am 4 December (Central and Victoria lines) 8.30pm 4 December – 4.29am 5 December (Central and Victoria lines) 8.30pm 10 December – 4.29am 11 December (Central and Victoria lines) 8.30pm 11 December – 4.29am 12 December (Central and Victoria lines) 8.30pm 17 December – 4.29am 18 December (Central and Victoria lines) 4.30am 18 December – 4.29am 19 December (Central, Jubilee, Northern, Piccadilly and Victoria lines) Why is the strike happening? The Rail, Maritime and Transport (RMT) union called the strikes to coincide with the reintroduction of Night Tube services on the Central and Victoria lines from the evening of Saturday 27 November, and on weekends throughout December. TfL says drivers will have to work about four Night Tube shifts a year. It has argued that all other Tube unions agreed to the change in rosters in May, which came after Night Tube staff were integrated into TfL’s “day Tube” workforce. However, the RMT says the changes have resulted in “unacceptable and intolerable demands” on its members.” https://inews.co.uk/news/tube-strike-friday-november-2021-time-london-underground-walkout-when-start-end-tfl-lines-1318536#:~:text=The%20action%20will,on%20its%20members.
