The RMT finds itself in a difficult place now the focus of media attention has moved on to nurses, ambulance crews and teachers.
The railway offer is better than that for those public sector workers, and nobody is interested in the technicalities of the terms and conditions argument.
Mick Lynch always wanted a cross-industry strike to make it more effective, but the public are heartily sick of the various unions making the railway unusable by staggering strikes across the industry.
Once an individual offer is accepted, the wider strike will collapse, and we seem to be closing in on that position, particularly on the NR side.
The strikes also mean that reductions in services are ever more probable, so union members will lose out anyway when services are permanently thinned out.
In those circumstances a "no redundancy" demand is simply unrealistic, as it would be in any other industry.
