Only higher-ups need the foresight to save themselves and the rest of the company by unseating this particular individual, otherwise there will be NO COMPANY (or at best we will be the embarrassing shadow of the giant we once were, like MEA, Gulf Air, etc.) so what's the point?
Choose one:
Remove the big problem- many smaller problems will be solved as a consequence- stay in business. At least keep your head above water for the time being.
Or
Implode in a most embarrassing public fiasco and slowly sink.
