I shouldn't be too concerned, jimmyg....
First Officers (brand new or well experienced) generally do as they are told when the chips are down, and if for some strange reason they do not, it really is quite simple to keep them headed in the right direction...just make sure that you, as the Commander, keep them PNF for as long as it takes for them to get the message.
Works every time.
Of course, they might go to the fleet manager an complain, but it has been my experience (as I'm sure it is with your good self) that these complaints generally fall on deaf ears.
