I think this is my question though. Is it better strategy to have one coordinated day when the railway is properly shut down with no services at all or ongoing action on alternate days persisting for a longer period, with part of the railway taking its strikes in turn?I wonder if there will be discussion to have a coordinated strike date with RMT (should it go ahead). Obviously it’s more disruptive (pretty much zero trains), but that is after all somewhat the point of industrial action.
The one day is a nuisance but once complete it is soon forgotten. Ongoing disruption until the aims are reached is an ongoing nuisance. Obviously, it runs the risk that one group could get a better deal and leave the group that doesn't get that deal left behind. (You can potentially see the risk that if signallers and drivers get a deal, all the 'nasty' threats to guards, ticket office staff etc could still go through with not much to be seen as profit from the strike action.)
