There is a great deal of confusion about the term Financial Core. Lots of folks are under the impression it’s a special form of union membership (in the case of us in the voiceover business in the USA that would be AFTRA and SAG) that allows one to work both union and non-union. This is simply not true. Financial Core is more correctly termed dues-paying non-member. Emphasis on the “non” part of non-member.
For a thorough explanation, I’ve never seen a better article that this one about financial core on the BizParents Foundation site. And my thanks to my friend Connie Terwilliger for posting a link to this article on the VO-BB.
