Fired from the companies they founded!? Not for a cause.
Some of them: Steve Jobs, Elon Musk, Uber founder.
These are not isolated cases. This may happen everywhere. To many founders?!
It happened to me twice: first in a financial institution and second in family corporation that owned subdivisions, memorial park, commercial complex, financial institutions. The engineers of the coup are now gone.
Caused by power struggle, politics, envy. Especially if the company is doing well.
