The BBC says it all:
London Underground workers are to take five days of strike action over Tube ticket office closures, the RMT Union has announced.
The row is about the closure of all 260 Tube ticket offices and 960 job cuts.
Members will walk out from 21:00 BST on 28 April for two days and again from the same time on 5 May for three days.
This follows over 40 meetings in the last two months between LU and the unions. LU have given a number of concessions, including a repeated guarantee of no compulsory redundancies and smaller stations being staffed at all times.
The RMT maintains that these plans mark 'only the first tranche of cuts' against LU workers.
