"...Can you build a house? Fix a car? Grow crops? Butcher an animal properly? Land an airplane?..."
You have a SERIOUSLY optimistic view of the Mad Max type aftermath of a nuclear apocalypse. Fix a car? Land a plane? Those questions imply an assumption on your part that an awful lot of support systems will have survived. (For instance, I'm not at all sure that fuel deliveries would continue to be made after a nuclear apocalypse. I'm even less certain that the electronic systems of most planes and autos will survive the nuclear unpleasantness unaffected.)
Sure, there is a spectrum of hands-on skills that could be important or not, depending on how much was blown to bits. My overall point is that "staffing coordinator" and "business analyst" are nowhere on that spectrum. Learn a trade as a hobby.
