Wensleydale,
One way interview soon followed - he didn't last long
I am hoping this chap had a history of avoiding flying without what you deemed to be a suitable reason. If this was a one off and it was me you can rest assured your caring leadership would have been been noted and following my silence at the one way interview raised a rank or two shortly after.
Yes I have experienced a similar situation and yes the ranks above helped me, but I did not make a habit of it and I made an enemy for the rest of that tour.
