Crow most recently opposed the ticket office closures yet statistics showed they're being used less and less. There were to be no compulsory redundancies and staff redeployed to be used more efficiently on the station itself. Whether they become any more helpful, knowledgeable and polite than the current dregs working there is yet to be seen. The two day strikes absolutely cripple commuting in London and make a usually stressful journey even worse.
I was last the member of a union in 2005 when I worked for CIS on Miller Street. They were about as useful as a chocolate fireguard when the redundancies and redeployment came in and no work place since has had such a group. We've never needed them.
