Ok, you're on a 3 on/off shift in the Artic, and it's been weathered out for 4 days in camp when your crew change is supposed to happen, and the twin otter can't get in to land at camp....explain for me the magic spell you cast that guarantees that crew change will take place on time?
Last time I looked, teleportation isn't real.
Or do you mean that you should be looking at the weather, and crew changing out early? Because I don't think the client is going to change their whole schedule around yours when sharing crew change charter flights. Is the cross-shift supposed to give up some of his days off early in that scenario, or is it only your own shift that shouldn't be interrupted?
#### happens sometimes.
