I don't know about California, but increasingly exotic dancers are suing for employment rights. E.g. http://www.nytimes.com/2013/09/11/nyregion/strippers-are-pro...

In many first world countries, both exotic dancers and (where legal) prostitutes have employment rights.

Its frequently an issue of dispute, though some of the items cited for Uber drivers don't apply -- e.g., the Uber no-tipping rule -- so the cases are not precisely analogous.
