Paul, I 100% agree with and have experienced all the things you've described. We've all had bad work experiences.
But you seem focused exclusively on the reading and training aspect.
I didn't find her complaints and demands about flying business class or being put in front of clients to deliver potentially tricky (not to mention "make or break") pricing information and not being given leadership opportunities without sufficient experience to be "dead-on accurate".
I'll also suggest that if any of your criticisms about badly written and/or out of date documentation were true for her, rather than just complaining about them she could have rolled up her sleeves and made or at least suggested some improvements. Which would demonstrate leadership.
Taken together, I'm sticking with my assessment.
