The trouble is that the board of directors has 2 separate parts, and the part that would raise the question of firing the CEO has to let the other part actually do the firing - and that part is controlled by schmucks whose campaign coffers were filled by the CEO’s schmoozing.
And there are other problems too. Some shareholders try to oust their Board of Directors as well as the CEO but fake shareholders are brought in by the boxfuls to negate what the real shareholders are trying to do...
All good point, but they’re also all good reasons why a lawsuit ain’t going to solve a damn thing for this corporation and this CEO.
