At the risk of dragging this off topic;
I do question your claim, but I'm sorry I don't know exactly how many service interruptions there have been. You appear to have a good idea, so please tell. I still very much doubt it is 2-3 times a week. Maybe I haven't been paying attention at work.
As Swanwick approaches it's third birthday, I am reminded of the fact that we are handling more traffic with less delays than recent years.
Moaning and scaremongering aren't going to get us anywhere. We have to get on with the job.
As we were so kindly reminded in an open letter to operational staff, management do not have to consult with our trade unions at all in changing WPs. However, they realise that if they don't, they will lose any fragments of support they currently cling to.
