I think WW can demonstrate that he has been entirely reasonable in his approach and done everything he has said he would do.
He has tried to engage with the unions, compromised a little on restoring crew complements on some services, made noises about the potential return of staff travel in some form, etc.
Now if all these perfectly reasonable attempts are turned down, does that open the door for SOSR? Could people be shooting themselves in the foot big time with this one?
