Workers have a right to get paid for their work, but that’s pretty much it. They don’t have a right to influence company policies because they do not own it. Asking workers for their opinion is just politeness, but not something company necessarily has to do.

By that logic, a monarch's subjects did not have a right to influence kingdom policies because they did not own it.

A monarch's subjects don't choose to become subjects and they typically can't leave. Workers can choose from many different employers, or become self employed.

So you support a dictatorship as long as it permits emigration? Not that monarchies actually had anything to do with that, serfdom was abolished in most places long before them.

Get rid of the workers and what do you have? A failed company. The workers are the most important part and without them the business cannot survive. The most important part of the business should have a say in the business.

You would need to replace the disgruntled opinionated workers with workers who were happy with their job. Its a tiny bit more effort but in the end the result would be the same
