Democracy exists or should exist outside the companies, creating the laws that constrain contract law.
Companies are basically one person (at the top) trading money for work with the people doing what they are paid for. The person doing the work could of course say hey I don't want to do this job I want to do something else instead but I want you to still pay me the same amount, or more. That wouldn't really be about democracy would it?
Employee protection laws are a different matter and are possible because we live in a democratic society, if we do.
One huge step towards democracy would be universal healthcare, which would make it easier for people to quit the job they don't think they should be doing.
Corporations are legally constituted. A society should be allowed to decide whether they want to grant corporations a license to operate or not and, if so, then under what conditions. After all, you can freely chose to accept the limitations of your corporate charter, or you can take a lovely hike without being granted one at all.
I don't think anybody is seriously suggesting that employees be able to do whatever they want without limit and still be entitled to a pay cheque from a corporation.
Just as nobody would suggest that some despicable organisation be granted a legal charter to perform some anti-social, destructive, or massively wasteful activities... (sarcasm alert!) :)
But I think that, despite taking different routes, we arrive at the same conclusion that, yes, there are also positive legislative actions that could be taken (healthcare, UBI, others) which would effectively incentivize decent corporate behaviour without needing to set specific new rules or limits.
