From what has been posted above, doest it not mean that Virgin has to reduce the amount of flights going crew down by 50%. If they dont then they have to up the crew down payments.
Unless average sickness is above 6.49% in which case nothing changes.
This gives me the impression that its not sickness that is causing most of the trouble regarding crew down but something the company is doing, perhaps not rostering enough crew for each flight.
Then again maybe the current sickness average is way above 6.49% (does anyone have the figure?). In which case this seems fair to me!!!
