So what are the manipulations?
Has he not pushed for more holiday for retained staff?
Compare the outcome to the manifesto RMT put forth before the strike. I'll help.
First paragraph makes no sense. Both Oyster and Bankcard are loaded with money, and topped up regularly. Well that isn't changed by a ticket office, a ticket office doesn't say "nah, go on, have this one on me". In fact reducing costs would mean that you might not need so much money. You don't have to regularly top up your oyster you can have 1 year at least, it can also be set to do so automatically. If the gates don't deduct the correct amount, the ticket office staff tell you to call the phone number or go online. This hasn't changed.
Second paragraph. I don't understand delays are helped by staff, the lack of them on the station, driving the train make no difference to me. The emergency response procedures I think are something which has to be better discussed. But they haven't done anything on about this.
Third, disabled? Erm not sure how that helps, either the station has the access or it doesn't, if you are say blind you have to give advance notice anyway. If you are poor? Yes all these ticket office staff help the poor people, buy, erm having them pay their above median wage, 35 hour week and massive holiday. That's helping the poor, in as much as pissing on them would.
Fourth paragraph, that makes no sense at all.
If we ever listened to people like this, we'd be stuck without the looms, the Luddite movement, like evolution deniers just boggle my mind with their willfill ignorance of history, mathematic theory, and reliable physics.
