SAG says you can work non-Union for minimum wage with no benefits! (red has been added to important quotes)
"Background Actors' Resources
BACKGROUND ACTORS ARE NOT COVERED BY SCREEN ACTORS GUILD THEATRICAL AND TELEVISION CODES IN THE STATES OF WASHINGTON, OREGON, ALASKA, MONTANA OR IDAHO REGARDLESS OF BUDGET.
* While the project itself may be a SAG production, the background actors are not covered by the SAG contracts.
* All wages and benefits are negotiable, subject to state law.
* SAG has no basis upon which to pursue claims for background actors under these agreements.
* Even if the project is a SAG production, background work will not result in a SAG voucher leading to SAG membership eligibility.
* This is true, regardless of the budget of the project.
* Because the SAG Codes do not cover background actors and SAG is not, therefore, attempting to organize these jobs, it is not a violation of Rule 18 for a SAG member to accept a job as a background performer in a SAG theatrical or television project in these Northwest states."
