What is the Union Security Clause?
The union security clause of the union codes requires that performers be members in Good Standing with the union. Clearance is the method by which the union enforces union security. Before talent can be employed on a union job, the cast must be cleared by the union. This means that they must be in good standing (dues paid up, not a must-join, etc). All that you have to do is fax to the union the name and social security number of the potential cast members. The union will reply quickly, usually in a matter of minutes. If any of the performers are not in good standing you cannot hire them. In the lingo of the biz the whole clearance process is called Doing Station 12s.
