I am generally against worker protection for things that are voluntarily agreed on.
The problem is that bosses can sneakily introduce things that weren't agreed on, and this is usually bad for the worker because the worker has less power in the relationship, there are frictions to switching jobs, they have leverage over your reputation, and resolving the dispute via government or the courts is impractical and expensive.
This can be thought of as a type of mild fraud, where two parties came to a contractual agreement that one party then violated (or perhaps it's a grey area that wasn't explicitly covered contractually).
This is why everyone should be in favor of some basic level of worker protection. Even if you're a hard libertarian - as they are purportedly against fraud, too.
