Unfortunately, there is no Ombudsman system except for the company’s owner and/or Board of Directors—both of whom can fire the CEO. I would point out that it is appalling that CEOs earn on average about $12 million per year. And, according to Statista:

“In 2022, it was estimated that the CEO-to-worker compensation ratio was 344.3 in the United States. This indicates that, on average, CEOs received more than 344 times the annual average salary of production and nonsupervisory workers in the key industry of their firm.”
