Arizona is a right-to-work state that welcomes both union and non-union film projects. “Right-to-work” essentially means that no one can be compelled to join a union, nor can employment be withheld because of membership or non-membership in a union, and further, that it is a matter of choice for the employer, employee and the production.  It is the responsibility of each production to make the appropriate contract and hiring determinations. It should be noted that it is illegal under Federal law for an employer to discriminate in regard to hire or tenure of employment so as to encourage or discourage membership in any organization.
