Be careful about suggestions that either one group or another will be stigmatised after this is all over. Remember that whatever your personal viewpoint, you will have to work together both before, through and after the strike period, and you will need to get on both professionally and personally. Difficult as it may be not to, setting against someone because they took a different viewpoint from you is corrosive and damaging. Accept that people's opinions will vary, and that they are as entitled to hold them as you are to hold yours.
While it is possible that individuals' cards could be marked because they struck/worked/abstained, it would profit no-one to do so, and would abosrb a lot of effort and energy better used getting things back on an even keel once this is all over. And, have no doubt, it will be over soon one way or another. If you are consumed by hatred of those who took a different standpoint from you, it is you who will be the poorer - and that's true whether you're CC, management, the Union or the Company!
As I have said, several times, the only way this will be solved is by discussion. The strike will have achieved something if it gets both parties back to the table, but its lack of clarity or stated aims, and the Union's obvious ignorance of what CC actually want, don't bode well for those who support a strike. Sadly, it seems that we will now have to wait until the 9th to see who comes out on top. Whatever the result on the day, I can't see any winners emerging from the dust. Everyone in Virgin will have lost in some way, and that loss will have been unnecessary and futile.
As for crewing ringing round, that does not imply any miscalculation on the Company's part. It simply means they are trying to refine their estimates (for that is all they are) of how many crew they can expect on the 9th, and thus determine both how many flights will actually operate, and with how many crew on each flight. It's one of the few sensible measures being taken while all the nastiness goes on.
