CASTING DIRECTORS: Can I add multiple unions to my project?

While a project can only be listed with one union, individual background roles within a SAG-AFTRA project can be listed as Union, Union / Non-Union, or Non-Union. 

When creating your project, list your project as SAG-AFTRA and include the contract type if possible.

While creating roles, if you are adding a Background role, you will see an option to list the individual role as SAG-AFTRA or Non-Union.
