Not a rhetorical question. I genuinely would like an explanation of how you can legally post "Applicants must understand there will be no compensation for this position" in a job posting, when minimum wage laws dictate the minimum wage that can be paid for employment.
Specifically, in California [1]:
> Although there are some exceptions, almost all employees in California must be paid the minimum wage as required by state law.
The 'exceptions' are for learners (those with little experience), the mentally ill, and the disabled, which all have different wage laws (none of which allow any of those groups to be employed for free either).
