In a long running dispute about the closure of ticket offices, the main drivers Union has called two sets of strikes – both in the working week and both much longer than in the past.
At present they are:
28 April – 2100 for 48 hours (ending 2100 on 30 April)
5 May – 2100 for 72 hours (ending 2100 on 8 May)
Typically TFL runs some services with drivers not in this Union, or Management staff.
