This kind of aside is what keeps me here, so I'll thank you for it :) > Each flow chart ends with a "If nothing failed a test, but the symptom persists, replace the entire part/assembly." I suppose this kind of does refute my point a little bit. Maybe the Tech Worker Handbook should have rules of thumb on when to quit – e.g. if the estimate for legal fees is going to be more than 1% of your salary, evaluate if makes more financial sense to quit your job and look for a new one instead. Of course, circumstances differ wildly between individuals, so anything more than a rule of thumb is not possible.
