My son is friends with the son of an ex Finance VP at Dell whom quit last year. We were chatting about dell and he basically said that the company is run by 4 people, none of which are MD. JC being one of them, Doug Schmitt I think was another and I forgot the other two lol... MD just cares about his billions and whatever needs to be done to increase his money is told to those 4; basically.
This is all a "DUH" but it was interesting to hear this from an ex finance VP.
But he was saying that no matter high up you are, what you want or say is moot unless these 4 people say it's not "moot." They dgaf about anyone or anything except the mass amounts of money they earn. MD only cares about his billions, and If it hurts their bank accounts then they will lay off thousands with no concern, cheap out on raises/promotions, etc etc etc...
Promotions are impossible to get now and those who get them are in countries that aren't the US. In Role promotions are basically non-existent as well. Not impossible but just not likely.
Long story short, the "main" people running the company only care about THEIR money. Not you, or any of the tends of thousands who make them that money.
