KittyBlue,
I totally understand where you are coming from with your post above but I also think Virgin has a responsibility and obligation to its employees to let them know that there will be changes to pairings and rosters which in turn means reduction in overnights. To date the communications in relation to the new KRONOS system has always been about "Crew will now get what they want", "Create your roster" etc.... There has never been a word of a new efficiency system resulting in the reduction of overnights.
I think its obvious that overnights are not guaranteed, but when you go from having 14 to having none thats a slight shock to the system. I guess the coming months will be interesting to see the outcome. Let's just wait and see...
